feat: security hardening, tests, doctor command, CI update, CHANGELOG

- Add AES-256-GCM encryption for API keys (internal/secret)
- Add dangerous command detection in terminal
- Add muyue doctor command for system health checks
- Add scanner TTL cache, orchestrator history mutex, shared HTTP client
- Deduplicate MCP config generation, refactor skills YAML parser
- Add XDG-compliant config dir with legacy migration
- Add cleanup on all TUI quit paths
- Add 8 test files (config, workflow, skills, orchestrator, version,
  platform, scanner, secret)
- Update CI to actions/setup-go@v5
- Add CHANGELOG.md, update README and Makefile
