feat: implement error-panel scanning and repair stubs

- Create error-panel-scan.ts with createScanForErrors function
- Create error-panel-repair.ts with createRepairHandlers function
- Both include comprehensive JSDoc comments explaining their purpose
- Fixes missing file imports in use-error-panel-main hook
- Build: passing ✓
- Audit: 0 issues ✓
