* feat: add minimal pre-commit infrastructure
- Add pre-commit configuration with essential checks only
- Check YAML, TOML, JSON syntax
- Check for merge conflicts and large files
- Enforce LF line endings (fix 2 test files with CRLF)
- Add debug statement detection
- Integrate ruff for Python formatting and linting
- Add GitHub workflow for pre-commit CI
- No unnecessary Python code changes
* fix: add explicit permissions to pre-commit workflow
- Set GITHUB_TOKEN permissions to read-only for contents
- Follows principle of least privilege
- Addresses CodeQL security recommendation
- Pre-commit checks only need to read code, not write
* fix: exclude test data from line ending modifications
- Exclude .proto files and test/data directories from mixed-line-ending hook
- Revert changes to test data files (traced_crash.proto, java_stacktrace.txt)
- These files need to preserve their original format for test integrity
- Binary proto files could be corrupted by line ending changes
* docs: add pre-commit hooks documentation to CONTRIBUTING.md
- Add pre-commit installation instructions to development setup
- Document pre-commit hooks in Code Quality Standards section
- Update submission workflow to include pre-commit checks
- Provide manual pre-commit run commands for contributors
* docs: streamline CONTRIBUTING.md for better readability
- Reduce from 214 to 124 lines (42% reduction) while keeping all essential info
- Consolidate setup instructions into concise Quick Start section
- Convert component descriptions to scannable table format
- Streamline testing strategy with clear requirements and timing
- Add back critical testing prerequisites (codequery, ripgrep, cscope)
- Create actionable Getting Help section with common troubleshooting
- Remove redundant command listings and verbose explanations
- Maintain all security requirements and essential workflows
