chore: sync .cursor/ directory with latest agents, commands, and skills

- Sync 13 agent files with updated descriptions and configurations
- Sync 23 command files with latest YAML frontmatter and content
- Sync 7 skill SKILL.md files with proper YAML frontmatter quoting
- Copy missing cpp-testing and security-scan skills to .cursor/
- Fix integration tests: send matching input to blocking hook test and
  expect correct exit code 2 (was 1)
