chore(husky): run Socket pre-commit checks and speed up test step

- Invoke .git-hooks/pre-commit for Socket security checks (API keys,
  .DS_Store, etc.) before lint/test.
- Pass --fast --skip-build to the staged test run so pre-commit stays
  quick now that build artifacts are reused across steps.
