v0.2.1

Fixes

• Documentation accuracy: fixed 14 factual inconsistencies across en/zh docs (version numbers, C++ patch count, CLI output model, MCP install instructions)
• CI stability: migrated to uv for reproducible builds, fixed ANSI test failures, added Python 3.14 to test matrix
• Skill install: simplified --platform claude to user-global (removed claude-global alias)

Housekeeping

• Updated project description
• Integration tests now have timeout + continue-on-error
• Added PyPI trusted publisher workflow (auto-publish on release)
