cli: worktree lock + dirty-tree preservation — stop pruning uncommitted work

Three behavior changes to the hermes -w worktree lifecycle:

1. Git-native locks. _setup_worktree now locks its worktree
   (git worktree lock --reason "hermes session pid=<pid>"), and
   _prune_stale_worktrees skips locked worktrees at ANY age — a lock
   from a live or crashed session means "do not touch". New helpers
   _lock_worktree / _unlock_worktree / _worktree_is_locked (fail-safe:
   any error reads as locked) / _worktree_is_dirty (fail-safe: any
   error reads as dirty).

2. Dirty trees are preserved. _cleanup_worktree previously destroyed
   worktrees with uncommitted changes if there were no unpushed
   commits; it now keeps the worktree, branch, and lock when the tree
   is dirty OR has unpushed commits, and prints manual cleanup hints
   (git worktree unlock + remove --force). The >72h "force remove
   regardless" prune tier is removed: pruning may only ever delete
   clean, unlocked, fully-pushed worktrees.

3. Branch deletion is gated on removal success. Both cleanup and
   prune previously deleted the branch without checking the
   git worktree remove returncode, dropping easy reachability of the
   commits even when removal failed; the branch is now only deleted
   after a successful remove.

-### Install with the standard installer
-
-For most contributors, the best development bootstrap is the same path users
-take: run the standard installer, then work inside the repository it cloned.
-The installer creates the Hermes venv, wires the `hermes` command, stamps the
-install method for `hermes update`, and clones the full git project into
-`$HERMES_HOME/hermes-agent` (usually `~/.hermes/hermes-agent`). That keeps your
-development environment on the same layout the CLI, updater, lazy dependency
-installer, gateway, and docs assume.
-
-```bash
-curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
-cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent"
-
-# Add dev/test extras on top of the standard install.
-uv pip install -e ".[all,dev]"
-
-# Optional: browser tools / docs site dependencies.
-npm install
-```
-
-After that, create branches and run tests from that checkout:

-```bash
-git checkout -b fix/description
-scripts/run_tests.sh
-```
-
-### Manual clone fallback
-
-Use this only if you intentionally do not want Hermes' managed install layout
-(for example, a throwaway clone inside a container or CI job). If you install
-this way, make sure you run the `hermes` entrypoint from this venv; running the
-system `python3 -m hermes_cli.main` can pick up unrelated system Python
-packages.
