feat(mcp): raise default tool-call timeout 120s -> 300s

Port from openai/codex#28234. Long-running MCP tools (web fetches,
sandboxed builds, deep-research servers) routinely exceed 120s, causing
spurious timeout failures. Codex bumped its default MCP tool timeout from
120 to 300 for the same reason.

- _DEFAULT_TOOL_TIMEOUT 120 -> 300 in tools/mcp_tool.py (per-server
  'timeout' config override unchanged)
- update test_default_timeout assertion
- document the default in mcp-config-reference.md

-# one tool call per turn multiplies the number of round-trips — and therefore

-"""Profile-scoped credential resolution for multi-profile gateway multiplexing.
-
-The multiplexing gateway serves many profiles from one process. Each profile
-has its own ``.env`` with its own provider keys and platform tokens, so we
-**cannot** union them into the process-global ``os.environ`` (that would leak
-profile A's keys to profile B's turns, and to every subprocess spawned with
-``env=dict(os.environ)``).
-
-This module provides a fail-closed, context-local secret scope:
-
-- ``set_secret_scope(mapping)`` installs the active profile's secrets for the
-  current task (a contextvar, so it propagates into the agent's worker thread
-  via ``copy_context()`` exactly like the HERMES_HOME override).
-- ``get_secret(name)`` reads from that scope. When multiplexing is **active**
-  and no scope is set, it RAISES rather than silently falling back to
-  ``os.environ`` — an un-migrated or newly-added call site fails loud at that
-  exact line instead of leaking another profile's value. When multiplexing is
-  **off** (the default), it transparently reads ``os.environ`` so the
-  single-profile gateway and every non-gateway caller behave exactly as before.
-
-Design rationale lives in ``docs/design/multiplexing-gateway.md`` (Workstream A).

-/**
- * remote-lifecycle.cjs
- *
- * Pure, electron-free remote Hermes dashboard lifecycle over SSH for Desktop
- * SSH remote mode. Composes an SshConnection (injected) with HTTP probes
- * through the established tunnel (injected fetch) and the served-token adoption
- * step (injected). Knows how to:
- *
- *   - locate the Hermes install on the remote (login-shell probe),
- *   - gate the remote platform to Linux/macOS via `uname`,
- *   - reuse an existing desktop-dedicated dashboard via a lockfile + an
- *     AUTHENTICATED /api/status probe (pid liveness alone is insufficient),
- *   - spawn a fresh detached `--isolated --port 0` dashboard and scrape its
- *     `HERMES_DASHBOARD_READY port=<n>` readiness line,
- *   - adopt the token the dashboard actually serves (served-token adoption),
- *   - clean up a stale dashboard only when it is provably ours.
- *
- * Electron-free so it can be unit-tested with `node --test`. main.cjs wires the
- * real SshConnection, fetch, adoptServedDashboardToken, and waitForHermes in.
- *
- * The minted HERMES_DASHBOARD_SESSION_TOKEN is the SPAWN credential. After
- * readiness the caller (or connect() here) runs served-token adoption against
- * the tunneled baseUrl and the SERVED token's fingerprint is what lands in the
- * lockfile — so the reuse probe checks the credential that actually
- * authenticates /api/ws, not the minted one (which the dashboard may regen).

- * main.cjs requires this and wires it into the electron-coupled lifecycle.
- *
- * Conventions mirrored from tools/environments/ssh.py:
- *   - ControlMaster=auto + ControlPersist so one TCP/auth handshake is reused
- *     across exec/forward operations.
- *   - Hashed control-socket filename under a short tmpdir to stay under the
- *     104-byte sun_path limit macOS enforces on Unix domain sockets
- *     (ssh.py:53-67 rationale applies verbatim).
- *   - BatchMode=yes for every programmatic invocation — a spawned ssh must
- *     never hang on an interactive prompt (passphrase / 2FA). If auth needs
- *     interactivity we fail fast and tell the user to load the key into their
- *     agent.

- * Host-key policy: StrictHostKeyChecking=accept-new (trust-on-first-use, log
- * the fingerprint), never `no`. A host-key *change* fails closed with the
- * verbatim OpenSSH error surfaced to the UI.
- *
- * Every operation is raced against a hard timeout. A half-open TCP connection

- * timeout is treated as connection-dead so the caller does a full reconnect
- * rather than retrying in place (VS Code's agent host does the same).
