Defame1297 af8b46cd57 chore(plugins): sync generated content mirrors
Regenerate plugins/*/skills/ from plugins/*/.apm/ after the previous
four commits, via scripts/sync-plugin-content.sh --all. The mirror is
generated output (ADR-0017) that check-plugin-content-sync's pre-push
hook diffs against .apm/; nothing here is hand-edited.

# Comparing two branches
The two-dot and three-dot forms mean different things and are easy to swap by accident — check the
direction before reporting a result.
- `rtk git log main..feature` — commits on `feature` that are not on `main`.
- `rtk git log feature..main` — the reverse direction: commits on `main` not on `feature`.
- `rtk git log --left-right main...feature` — both diverging sets at once (symmetric difference).
- `rtk git diff main...feature` — the diff from the common ancestor to `feature`'s tip, which is what
a reviewer sees, rather than the diff between the two tips.
- `rtk git merge-base main feature` — print the common ancestor commit.
