chore(marketplace): add publish-plugin, rewrite init.sh, cleanup obsolete plugins

- Add publish-plugin: marketplace publish + Feishu bot notification
- Rewrite init.sh: SSE-first, fixed prod API, remove env selection
- Update CLAUDE.md, README.md, claude-config.yaml
- Update skills: req-plugin, req-prd-plugin, pull-request-plugin
- Delete sync-skills.sh (obsolete)
- Delete deprecated plugins: skills-ops/*, skills-projects/*, old skills-dev/req duplicates
- Regenerate marketplace.json (27 plugins)
