fix: broken cross-references, version sync, and enhanced command validator

- Fix /build-and-fix → /build-fix in tdd.md, plan.md (+ cursor, zh-CN)
- Fix non-existent explorer agent → planner in orchestrate.md (+ cursor, zh-CN, zh-TW)
- Fix /python-test → /tdd in python-review.md (+ cursor, zh-CN)
- Sync package.json version from 1.0.0 to 1.4.1 to match plugin.json
- Enhance validate-commands.js with cross-reference checking:
  command refs, agent path refs, skill dir refs, workflow diagrams
- Strip fenced code blocks before scanning to avoid false positives
- Skip hypothetical "Creates:" lines in evolve.md examples
- Add 46 new tests (suggest-compact, session-manager, utils, hooks)
