Add pre-commit hook and test runner

✅ Pre-commit Hook:
- Automatically runs tests before every commit
- Blocks commits if any tests fail
- Provides helpful error messages and guidance
- Can be bypassed with --no-verify (not recommended)

✅ Test Runner Script:
- Comprehensive test suite runner (scripts/run-tests.sh)
- Runs different test categories separately
- Provides detailed reporting and success/failure tracking
- Helps identify which specific tests are failing

✅ Quality Assurance:
- Ensures no broken code is committed
- Enforces test-driven development
- Maintains code quality standards
- Prevents regressions from being introduced

This implements the rule: ALL TESTS MUST PASS BEFORE COMMITTING
