fix(git): scope git-workflow's trigger to ambiguity rather than to its domains

git-workflow's description enumerated the six domains it exists to route away
from, so it competed for selection with the very skills it should be handing
off to. It now triggers on the case it actually serves: an interactive request
whose domain is not yet clear.

Also clears frontmatter drift across the plugin and removes duplicated guidance
in pc-run that had diverged from its reference.

 Gates:
 
 - **`move`, `remove` — the main worktree cannot be moved or removed.** Only linked worktrees, the ones `git worktree add` created, are candidates.
 - **`add`, `move`, `remove` — escalate force flags one step at a time.** `-f` overrides a safeguard such as an unclean tree; `move` and `remove` need `-ff` on top of that when the worktree is locked. Confirm with the user before either — both discard state.
-- **`lock`, `move`, `remove`, `repair` — identify a worktree by full path, unique basename, or unique partial path.** An ambiguous name errors rather than picking; `git worktree list` shows the usable identifiers.
-- **`add` — the bare-name tracking shortcut needs exactly one remote.** `git worktree add <path> <branch>` sets up tracking only when `<branch>` is absent locally, no `-b`/`-B`/`-d` is given, and exactly one remote carries the name. With several, it fires only if `checkout.defaultRemote` names one. When the remote is ambiguous or unknown, use `--track -b`.
 - **`add` — lock at creation, not after.** `git worktree add --lock` is atomic, where add-then-`lock` leaves a window in which the worktree is unprotected.

 `--guess-remote` covers the *other* spelling — `git worktree add <path>` with no `<commit-ish>` at
 all. It bases the new branch on the remote-tracking branch matching `$(basename <path>)` when
