feat: scope npm package as @dietrichgebert/ponytail

Publish under a scope you own outright instead of opencode-ponytail (which
sits on a third-party npm account). Matches the GitHub handle and repo.
publishConfig.access is already public, which scoped public packages need.

+| Codex | `codex plugin remove ponytail` |
+| Pi agent | `pi uninstall ponytail` |
+| Cursor / Windsurf / Cline / etc. | Delete the copied rule file |
+
+These remove the plugin's own files. They leave behind a small amount of state ponytail writes outside the plugin folder: the mode flag, `~/.config/ponytail/config.json`, and (if you accepted the setup nudge) a `statusLine` entry in `~/.claude/settings.json`. Run `node scripts/uninstall.js` to clean those up too. **Run it before the host remove command above** — the script is itself a plugin file, so removing the plugin first deletes it (or run it from a separate clone of this repo). It only removes the statusLine entry if it points at ponytail's own script, so a statusline you set up yourself is left untouched.
