- Remove no-op `"hooks": {}` from .claude-plugin/plugin.json (auto-discovery from hooks/hooks.json picks up the SessionStart hook).
- Remove redundant `version` from marketplace.json plugin entry; plugin.json is the source of truth per the spec.
- Sync description / longDescription across .claude-plugin and .codex-plugin manifests so all surfaces show the same copy.
