chore: enhance pre-commit hooks for improved code quality

Add several pre-commit checks to strengthen code quality and security:
- Limit large file commits to 500KB
- Detect case conflicts, merge conflicts and broken symlinks
- Validate YAML files and detect private keys
- Standardize line endings to LF
- Ensure executables have shebangs

The existing trailing whitespace check remains unchanged.
