Update documentation: correct MCP tool count to 9 tools

- Update mcp/README.md: 8 tools → 9 tools, add upload_skill docs
- Update docs/MCP_SETUP.md: verify section lists all 9 tools
- Update docs/CLAUDE.md: MCP tool references updated
- Add upload_skill to tool listings and examples
- Update test coverage count: 31 → 34 tests

All documentation now accurately reflects the current feature set.
