feat: expand MCP tool coverage from 93 to 299 tools

Fork the official gitea-mcp and massively extend API coverage:

- Organization: orgs, members, teams, hooks, blocks, activity (34 tools)
- User: profile, followers, keys, emails, repos, blocks (30 tools)
- Repository: collaborators, webhooks, branch/tag protection, deploy keys,
  topics, git refs/trees/notes, commit status, stars/watchers, forks,
  transfers, mirrors, templates (53 tools)
- Issue: reactions, pins, subscriptions, timeline, templates (16 tools)
- Notifications: list, check, read, repo-scoped (7 tools)
- Settings: API, attachment, repo, UI settings (4 tools)
- Packages: list, get, delete, files, latest, link/unlink (7 tools)
- Miscellaneous: server version, gitignore/label/license templates,
  markdown/markup rendering, node info, signing keys (12 tools)
- Admin: user/org/repo CRUD, system webhooks, cron tasks, unadopted
  repos, emails, badges (23 tools)
