chore(deps): consolidate dependency updates (#489)

- serialize-error 11.0.3 → 13.0.1: fixes recursive error property
  serialization in background tasks (major bump, Node 20 compatible)
- nanoid 5.0.8 → 5.1.9: performance improvements (~75% faster
  customAlphabet), TS type improvements
- helmet 8.0.0 → 8.1.0: better CSP error messages
- simple-git-hooks 2.11.1 → 2.13.1: ESM config support, env var fixes
- pnpm/action-setup v5 → v6: forward-compatible CI action

Skipped:
- typescript 5.6.3 → 6.0.3: major version, needs separate PR
- @types/node 22.9.0 → 25.6.0: runtime is Node 20, types for 25
  would create false confidence
