chore: remove repo-local ship-pr skill

AGENTS.md

@@ -64,15 +64,6 @@ Project-specific Claude skills live under [`.claude/skills/`](.claude/skills/):
 - `bootstrap-feature` — how to add a CLI command end-to-end.
 - `architecture-review` — what to check when reviewing a PR against
   project invariants.
-- `ship-pr` — canonical post-edit flow: push → `gh pr create` → wait
-  for CI → review the diff → triage (self-fix small stuff, escalate
-  decisions, merge directly when clean) → `gh pr merge --squash` →
-  local cleanup. Use this instead of calling `gh pr create` /
-  `gh pr merge` directly. **Do not use `--auto`** — it skips the
-  review gate, which is the point of having this skill on top of the
-  branch-protection rules in [`docs/MERGE_POLICY.md`](docs/MERGE_POLICY.md).
-  **Do not ask the user to confirm a clean merge** — the loop closes
-  itself when there is nothing to decide.
