chore(catalog): sync counts to 62 agents / 78 commands / 235 skills

Auto-generated via `node scripts/ci/catalog.js --write --text`
after the react track additions:

- 2 new agents: react-reviewer, react-build-resolver (60 -> 62)
- 3 new commands: react-build, react-review, react-test (75 -> 78)
- 3 new skills: react-patterns, react-performance, react-testing
  (232 -> 235)

Files updated by the catalog sync:
- .claude-plugin/plugin.json description string
- .claude-plugin/marketplace.json plugin description
- README.md quick-start summary, project tree, feature parity tables
- README.zh-CN.md quick-start summary
- AGENTS.md project structure summary
- docs/zh-CN/README.md parity table
- docs/zh-CN/AGENTS.md project structure summary

All counts now match the filesystem catalog (verified by
ci/catalog.test.js).
