chore(plugins): sync generated content mirrors

Regenerates `plugins/*/skills`, `plugins/*/agents`, both per-plugin `plugin.json` manifests and the
two marketplace mirrors from `.apm/` per ADR-0017, via `scripts/sync-plugin-content.sh --all`.

The manifests matter beyond tidiness here: `plugin.json` carries the plugin version and wins over
the marketplace entry at install time (calculatePluginVersion precedence). Until this ran, the patch
bumps in the preceding commit were inert for anyone installing these plugins.

 - **Uncommitted changes abort a switch.** `git switch` refuses rather than clobbering conflicting local edits. Offer to stash and retry — forcing the checkout past it is how work disappears.
-- **A branch and a tag can carry the same name.** Detect it before acting — `rtk git branch --list <name>` and `rtk git tag --list <name>`; output from both means the name is ambiguous. Prefer `git switch` over `git checkout`, and where a command accepts either ref, disambiguate with `refs/heads/<name>` or `refs/tags/<name>`.
+- **A branch and a tag can carry the same name.** Detect it before acting — `git branch --list <name>` (bare, not `rtk`: rtk prints a phantom `* ` line even on no match, which reports every name as ambiguous — ADR-0023) and `rtk git tag --list <name>`; output from both means the name is ambiguous. Prefer `git switch` over `git checkout`, and where a command accepts either ref, disambiguate with `refs/heads/<name>` or `refs/tags/<name>`.
 - **`main` and `master` are a refusal, not a gate.** Force-pushing, force-deleting, or renaming them is rejected even when the caller passes `confirm: true` — no flag makes the remote's history recoverable. Offer a new branch instead.
