feat: enhance type safety and add package metadata

[Mohammad-Faiz-Cloud-Engineer]

Changes

• Enhanced TypeScript strict mode with noUncheckedIndexedAccess, noImplicitReturns, and noFallthroughCasesInSwitch
• Added NPM package metadata: author, repository, bugs, and homepage fields
• Improved CLI error logging with optional DEBUG mode for skipped folders
• Added Python type hints to search.py and core.py for better IDE support
• Fixed type safety issue in extract.ts: added null check for dirs[0]
• Fixed type mismatch in detect.ts: changed detected[0] to detected[0] ?? null

Bugs Fixed

1. Potential undefined access in ZIP extraction (cli/src/utils/extract.ts:123)

   • Added null check to prevent crash when accessing dirs[0]
   • Found by noUncheckedIndexedAccess TypeScript flag

2. Type mismatch in AI type detection (cli/src/utils/detect.ts:56)

   • Fixed type incompatibility between AIType | undefined and AIType | null
   • Found by noUncheckedIndexedAccess TypeScript flag

Testing

• ✅ TypeScript compilation: 0 errors, 0 warnings
• ✅ Python scripts: All tests passing
• ✅ Search functionality: Tested with real queries
• ✅ Design system generation: Generates complete output
• ✅ NPM package validation: All metadata valid
• ✅ No breaking changes
• ✅ 100% backward compatible
