fix: resolve all linting and TypeScript issues

- Rename fetch import to fetchOpenGraph to avoid global variable conflict
- Replace any types with proper Record<string, unknown> types
- Add proper type guards for OpenGraph data extraction
- Remove unused CACHE_TTL variable
- Fix TypeScript null assignment error in opengraphEnhancer
- All linting rules and type checks now pass
