Replaces the hand-rolled marketplace validator and bot-based bump
workflow with the shared composite actions (pinned at f846a0b).
marketplace.json:
- 62 external entries that were missing a `sha` are now pinned to
their current upstream HEAD (resolved via git ls-remote).
Workflows:
- validate-plugins.yml: invariants I1-I11 + claude plugin validate +
diff-gated clone-at-SHA validation of changed external entries.
SHA-pin (I5) is a hard error. I8/I11 stay warnings until the 15
known data issues (vendored dirs without manifests; one dotted
name) are cleaned up.
- bump-plugin-shas.yml: bot-free weekly refresh. Validates each new
SHA with claude plugin validate before opening one PR; works with
the default GITHUB_TOKEN (contents:write + pull-requests:write).
- scan-plugins.yml: Claude policy scan of changed external entries.
Non-blocking; graceful no-op if ANTHROPIC_API_KEY isn't set.
Removed:
- validate-marketplace.yml + the two TS helper scripts (superseded
by step 11/20 of validate-plugins).
validate-frontmatter.yml is kept — it's complementary (targeted
checks on agent/skill/command files for in-repo plugins).
