docs(skills): add disallowed-tools field and simplify bundled skill

Browse Source 
- Bump version to v2.1.158
- Add disallowed-tools frontmatter field (15 -> 16): tools removed from the pool
  while skill is active, clears on next message
- Add simplify bundled skill (9 -> 10): cleanup-only review across four parallel
  agents; no longer hunts correctness bugs as of v2.1.154 (use /code-review)
