Allow empty Superpowers hooks manifest

Publish the completed third-party source refresh after Superpowers 6.1.1 changed its Codex manifest to use an empty no-op hooks object instead of a hooks file path.

Constraint: Current Codex CLI installs superpowers@eapil-skill-market with hooks: {}, while the marketplace validator still rejected empty inline hooks objects.
Rejected: Restore the old hooks directory by hand | Upstream no longer declares those Codex hook files, and hand-restoring generated content would drift from source.
Confidence: high
Scope-risk: moderate
Directive: Empty hooks objects are placeholders; allow them but do not count them as the plugin's only effective component.
Tested: /Users/eapil/git/keyinfo/.venv/bin/python3 scripts/validate_marketplace.py; rg public-secret scan; git diff --check; Codex temp CODEX_HOME marketplace add/list/add superpowers@eapil-skill-market.
Not-tested: Interactive Superpowers skill invocation inside a live Codex thread.
