chore: add GORM security scanner and pre-commit hook

- Introduced a new script `scan-gorm-security.sh` to detect GORM security issues and common mistakes.
- Added a pre-commit hook `gorm-security-check.sh` to run the security scanner before commits.
- Enhanced `go-test-coverage.sh` to capture and display test failure summaries.
