fix(cli): /plugins shows installed-but-not-enabled plugins

The /plugins slash command read from the live PluginManager, which only
knows about *loaded* plugins. A freshly-installed plugin that hadn't been
enabled yet showed 'No plugins installed. Drop plugin directories into
~/.hermes/plugins/' — even though it was on disk and a valid plugin.

Switch to the same disk-discovery path as 'hermes plugins list'
(_discover_all_plugins + enabled/disabled sets + _plugin_status), so an
installed plugin now appears with its activation state ([not enabled],
enabled, or disabled) plus the exact enable command.

Default the quick /plugins view to user-installed plugins and summarize
bundled providers/platforms on one line (the full catalog stays behind
'hermes plugins list') so the output isn't drowned by 60+ bundled
provider plugins.

 **Never give up on the right solution.**
 
-## What Hermes Is
-
-Hermes is a personal AI agent that runs the same agent core across a CLI, a
-messaging gateway (Telegram, Discord, Slack, and ~20 other platforms), a TUI,
-and an Electron desktop app. It learns across sessions (memory + skills),
-delegates to subagents, runs scheduled jobs, and drives a real terminal and
-browser. It is extended primarily through **plugins and skills**, not by
-growing the core.
-
-Two properties shape almost every design decision and are the lens for
-reviewing any change:
-
-- **Per-conversation prompt caching is sacred.** A long-lived conversation
-  reuses a cached prefix every turn. Anything that mutates past context,
-  swaps toolsets, or rebuilds the system prompt mid-conversation invalidates
-  that cache and multiplies the user's cost. We do not do it (the one
-  exception is context compression).
-- **The core is a narrow waist; capability lives at the edges.** Every model
-  tool we add is sent on every API call, so the bar for a new *core* tool is
-  high. Most new capability should arrive as a CLI command + skill, a
-  service-gated tool, or a plugin — not as core surface.
-
-## Contribution Rubric — What We Want / What We Don't
-
-This is the project's intent layer. Use it two ways:
-
-1. **For humans and for your own work** — what gets merged and what gets
-   rejected, so a contribution aims at the target.
-2. **For automated review (the triage sweeper)** — guidance on when a PR is
-   safe to close on the three allowed reasons (`implemented_on_main`,
-   `cannot_reproduce`, `incoherent`) and, just as important, **when NOT to
-   close** one. Taste-based "we don't want this / out of scope" closes are NOT
-   an automated decision — those stay with a human maintainer. The sweeper's
-   job here is to recognize design intent and *avoid wrongly closing a
-   legitimate contribution*, not to make the won't-implement call itself.
-
-Read the balance right: Hermes ships a **lot** — most merges are bug fixes to
-real reported behavior, and the product surface (platforms, channels,
-providers, models, desktop/TUI features) expands aggressively and on purpose.
-The restraint below is aimed squarely at the **core agent + the model tool
-schema**, the one place where every addition is paid for on every API call.
-"Smallest footprint" governs *how a capability is wired into the core*, NOT
-whether the product is allowed to grow. We are expansive at the edges and
-conservative at the waist.
-
-### What we want
-
-- **Fix real bugs, well.** The bulk of what lands is `fix(...)` against an
-  actual reported symptom. A good fix reproduces the symptom on current
-  `main`, points to the exact line where it manifests, and fixes the whole bug
-  class — sibling call paths included — not just the one site the reporter hit.
-- **Expand reach at the edges.** New platform adapters, channels, providers,
-  models, and desktop/TUI/dashboard features are welcome and land routinely,
-  including large ones (a new messaging channel, a session-cap feature, a
-  Windows PTY bridge). Breadth in the product is a goal, not a footprint
-  concern — as long as it integrates with the existing setup/config UX
-  (`hermes tools`, `hermes setup`, auto-install) rather than bolting on a raw
-  env var.
-- **Refactor god-files into clean modules.** Extracting a multi-thousand-line
-  cluster out of `cli.py` / `run_agent.py` / `gateway/run.py` into a focused
-  mixin or module is wanted work, even when the diff is huge and mechanical
-  (large `+N/-N` refactors merge regularly). The "every line traces to the
-  request" test applies to *feature* PRs; a declared refactor's request IS the
-  extraction.
-- **Keep the core narrow.** New *model tools* are the expensive exception —
-  every tool ships on every API call. Prefer, in order: extend existing code →
-  CLI command + skill → service-gated tool (`check_fn`) → plugin → MCP server
-  in the catalog → new core tool (last resort). See "The Footprint Ladder."
-- **Extend, don't duplicate.** Before adding a module/manager/hook, check
-  whether existing infrastructure already covers the use case. When several PRs
-  integrate the same *category*, design one shared interface instead of merging
-  them one at a time (see the ABC + orchestrator note under the Footprint
-  Ladder).
-- **Behavior contracts over snapshots.** Tests should assert how two pieces of
-  data must relate (invariants), not freeze a current value (model lists,
-  config version literals, enumeration counts). See "Don't write
-  change-detector tests."
-- **E2E validation, not just green unit mocks.** For anything touching
-  resolution chains, config propagation, security boundaries, remote
-  backends, or file/network I/O, exercise the real path with real imports
-  against a temp `HERMES_HOME`. Mocks hide integration bugs.
-- **Cache-, alternation-, and invariant-safe.** Preserve prompt caching, strict
-  message role alternation (never two same-role messages in a row; never a
-  synthetic user message injected mid-loop), and a system prompt that is
-  byte-stable for the life of a conversation.
-- **Contributor credit preserved.** Salvage external work by cherry-picking
-  (rebase-merge) so authorship survives in git history; don't reimplement from
-  scratch when you can build on top.
-
-### What we don't want (rejected even when well-built)
-
-- **Speculative infrastructure.** Hooks, callbacks, or extension points with no
-  concrete consumer. Adding a hook is easy; removing one after plugins depend
-  on it is hard. A hook is NOT speculative if a contributor has a real, stated
-  use case — even if the consumer ships separately.
-- **New `HERMES_*` env vars for non-secret config.** `.env` is for secrets
-  only (API keys, tokens, passwords). All behavioral settings — timeouts,
-  thresholds, feature flags, display prefs — go in `config.yaml`. Bridge to an
-  internal env var if the mechanism needs one, but user-facing docs point to
-  `config.yaml`. Reject PRs that tell users to "set X in your .env" unless X
-  is a credential.
-- **A new core tool when terminal + file already do the job, or when a skill
-  would.** If the only barrier is file visibility on a remote backend, fix the
-  mount, not the toolset.
-- **Lazy-reading escape hatches on instructional tools.** No `offset`/`limit`
-  pagination on tools that load content the agent must read fully (skills,
-  prompts, playbooks). Models will read page 1 and skip the rest.
-- **"Fixes" that destroy the feature they secure.** A mitigation that kills the
-  feature's purpose is the wrong mitigation. Read the original commit's intent
-  (`git log -p -S`) before restricting behavior; find a fix that preserves the
-  feature.
-- **Outbound telemetry / usage attribution without opt-in gating.** No new
-  analytics, third-party identifier tagging, or attribution tags until a
-  generic user-facing opt-in (config gate + setup prompt + `hermes tools`
-  toggle) exists. Park behind a label, do not merge.
-- **Change-detector tests, cache-breaking mid-conversation, dead code wired in
-  without E2E proof, and plugins that touch core files.** Plugins live in their
-  own directory and work within the ABCs/hooks we provide; if a plugin needs
-  more, widen the generic plugin surface, don't special-case it in core.
-
-### Before you call it a bug — verify the premise (and when NOT to close)
-
-The most common reason a well-written PR gets closed is not code quality — it
-is that the change is built on a **wrong premise**, or it treats an
-**intentional design as a gap**. These patterns cut both ways: they tell a
-human reviewer what to scrutinize, and they tell the automated sweeper when a
-PR is NOT safe to close as `implemented_on_main` / `cannot_reproduce` (when in
-doubt, leave it open for a human). They are distilled from real closes.
-
-- **"Intentional design, not a gap."** A limitation that looks like an
-  oversight is often deliberate. Before "fixing" a missing link or a
-  restriction, ask whether the isolation IS the design. Example: profiles are
-  independent islands on purpose — a PR adding live config inheritance from the
-  default profile was closed because coupling profiles together is exactly what
-  the design prevents (the copy-at-creation `--clone` path already covers the
-  legitimate "start from my default" case). Read the original commit's intent
-  (`git log -p -S "<symbol>"`) before assuming something is unfinished.
-- **"The premise doesn't hold against how X actually works."** A PR's
-  justification frequently rests on a wrong mental model of an existing
-  mechanism. Trace the real code/runtime before accepting the rationale. Two
-  real closes: a rate-limit "re-probe during cooldown" PR (the breaker only
-  trips on a *confirmed-empty* account bucket, so re-probing just hammers a
-  bucket we've already proven empty); a usage-accumulation fix whose new branch
-  **never executes at runtime** because an earlier guard already popped the
-  state it depended on. If you can't point to the exact line where the bug
-  manifests AND show the fix changes that line's behavior, you haven't verified
-  the premise.
-- **"This fix was wrong — the absence/omission was deliberate."** Adding the
-  obvious-looking missing piece can break things the omission was protecting.
-  Example: restoring "missing" `__init__.py` files made a test tree importable
-  as a dotted package that shadowed the real plugin, deleting its `register()`
-  at import time. The absence was load-bearing.
-- **"Overreached / resurrected an approach we'd moved past."** Scope creep that
-  supersedes an agreed-on base, or revives a direction the maintainers
-  deliberately closed, gets rejected even when the code works. Keep the change
-  to the narrow piece that was actually agreed; offer the rest as a focused
-  follow-up.
-
-The throughline: **verify the claim AND the intent against the codebase before
-writing or merging a fix.** A confirmed reproduction on current `main` plus a
-line-level account of where the fix acts beats a plausible-sounding rationale
-every time. When in doubt about intent, it is cheaper to ask than to ship a
-fix that fights the design.
-
-### The Footprint Ladder (new capability decision)
-
-Each rung adds more permanent surface than the one above. Choose the highest
-(least-footprint) rung that correctly solves the problem:
-
-1. **Extend existing code** — the capability is a variation of something that
-   already exists. Zero new surface.
-2. **CLI command + skill** — manages config/state/infra expressible as shell
-   commands. The agent runs `hermes <subcommand>` guided by a skill. Zero
-   model-tool footprint. Default choice for subscriptions, scheduled tasks,
-   service setup. Examples: `hermes webhook`, `hermes cron`, `hermes tools`.
-3. **Service-gated tool (`check_fn`)** — needs structured params/returns AND
-   only appears when a prerequisite is configured. Zero footprint otherwise.
-   Examples: Home Assistant tools (gated on token), memory-provider tools.
-4. **Plugin** — third-party/niche/user-specific capability that doesn't ship in
-   core. Lives in `~/.hermes/plugins/` or a pip package, discovered at runtime.
-5. **MCP server (in the catalog)** — if the capability genuinely needs to be a
-   tool (structured I/O the agent invokes) but isn't core-fundamental, prefer
-   building it as an MCP server and adding it to the MCP catalog over growing
-   the core toolset. The agent connects to it through the built-in MCP client;
-   zero permanent core-schema footprint, and it's reusable by any MCP host.
-6. **New core tool** — only when the capability is fundamental, broadly useful
-   to nearly every user, and unreachable via terminal + file (or an MCP server).
-   Examples of correct core tools: terminal, read_file, web_search,
-   browser_navigate.
-
-When 3+ open PRs try to integrate the same *category* of thing (memory
-backends, providers, notifiers), don't merge them one at a time — design an
-ABC + orchestrator, wrap the existing built-in as the first provider, and turn
-the competing PRs into plugins against that interface.
