feat: Improve Anime-Sama search with fuzzy matching

Replace direct URL conversion with official Anime-Sama search API that
handles typos, partial matches, and returns multiple results with cover images.

Changes:
- Use /template-php/defaut/fetch.php API endpoint for search
- Parse HTML search results to extract title, URL, and cover image
- Return multiple results instead of single direct match
- Support for fuzzy matching (e.g., "hell paradise" finds "Hell's Paradise")

Examples:
- "hell paradise" → finds "Hell's Paradise" (handles missing 's')
- "one pie" → finds "One Piece" (handles incomplete words)
- "dragon" → returns 5 Dragon Ball series with cover images
