Album/Track search

[boldandbrad]

Describe the problem
Users often can't remember exact track or album names, making CLI input tedious or impossible for long/cryptic titles. There's no interactive way to search last.fm directly within spin.

Describe the solution you'd like
Add a TUI mode search command that allows users to interactively search last.fm for albums and tracks using a fuzzy-finding algorithm as they type. From the search results, users can:

• Select a track/album to begin the relevant scrobble flow (TUI mode)
• Add it as a favorite (requires Favorites #7 - Favorites)

Example:

spin search
[search input field with live results below]
> Comfortably Numb
  Pink Floyd - Comfortably Numb (track)
  Pink Floyd - The Wall (album)
  Numb - Linkin Park (track)
  
  [select with arrow keys, enter to confirm]

Describe alternatives you've considered

• Typing out full names manually (error-prone for long/cryptic titles)
• Leaving the terminal to search last.fm in a browser, then returning to scrobble
• Using --exact-match flags if they existed (they don’t)

Additional context/considerations

• This feature depends on Favorites #7 (Favorites) being implemented first, as users should be able to save search results as favorites
• Consider debouncing API calls to avoid rate limiting. If rate limits are still a concern or if the last.fm api doesn’t provide an elegant way to implement this. We may need to look into integrating with Discogs or other data providers.
• Fuzzy matching should prioritize relevance over simple substring matching
• Should support both album and track search with optional flag (--album, --track) or unified results
