Add opt-in raw-git nudge hook, independent of anti-chaining hook

Forces a normal confirmation prompt (never a silent block, never a silent
allow) when Bash runs raw git instead of git_cmd.sh, worded more
insistently when the subcommand is one the wrapper already supports.
Raw git stays a valid fallback for unsupported subcommands and
unregistered repos - a hard deny would remove that fallback entirely.

Also documents in SKILL.md that repo ambiguity (which registered repo is
meant, or none at all) must be resolved by asking the user rather than
guessing - a hook only sees the literal command string, not the
conversation, so that judgment can't live in the hook itself.

+## When it's unclear which repo is meant

+Don't guess. If a task says "the repo" or otherwise implies a repo without
+naming one, and it's genuinely ambiguous which registered repo (if any) it
+refers to, or the request's context doesn't clearly match any registered
+repo at all, ask the user before picking a `--repo` or falling back to raw
+git. Concretely, this is already handled operationally rather than needing
+new logic: call `git_cmd.sh` without `--repo` and let it resolve —
+`resolve_repo_path` in `_lib.sh` errors out listing every registered name
+when more than one repo is configured and none was specified, and errors
+saying none are registered when the config is empty. Either error is the
+signal to ask the user which repo (or whether to register a new one),
+rather than picking one, or reaching for raw git, on your own.

+## The raw-git nudge hook
+
+Optional, offered during `/git-manager:setup`, independent of the
+anti-chaining hook above (you can install neither, either, or both). If
+installed, it watches every Bash command and, when it sees raw `git` used
+instead of `git_cmd.sh`, forces the normal confirmation prompt instead of
+letting whitelist matching decide — the same "never silently block, never
+silently allow" behavior as the anti-chaining hook.
+
+This is deliberately **not** a hard block. Raw git stays a legitimate
+fallback for subcommands `git_cmd.sh` doesn't support (`stash`, `merge`,
+`rebase`, `reset`, ...) and for repos that aren't registered yet — a full
+block would remove that fallback entirely. What the hook does instead is
+make sure raw git is never invisible: every time it's used, it's a
+confirmed, visible choice, worded more insistently when the subcommand is
+one `git_cmd.sh` already supports (in which case there's rarely a good
+reason to have bypassed it) and more permissively otherwise.
+
+What this hook can't do — and isn't trying to do — is figure out from the
+surrounding conversation whether raw git was actually the right call here.
+It only ever sees the literal Bash command text, not the request that led
+to it; that kind of judgment is the skill's own job (see `SKILL.md`), and
+this hook is just the backstop for when that judgment gets skipped.
