feat(marketplace): add lean/full profile switching for token optimization

- Add marketplace-lean.json (6 plugins) and marketplace-full.json (12 plugins)
- Add .mcp-lean.json (gitea only) and .mcp-full.json (5 servers)
- Create scripts/switch-profile.sh for easy profile switching
- Update sprint-status.md with conditional skill loading
- Set lean profile as default (~14k token savings)

Lean profile includes: projman, git-flow, pr-review, clarity-assist,
code-sentinel, doc-guardian
