Group metadata tests under tests/metadata
- Move the metadata and MusicBrainz-related tests into a dedicated tests/metadata subfolder.
- Keep the rest of the suite flat for now.
- Preserve the existing test filenames so the change stays organizational rather than behavioral.

"""Tests for the MusicBrainz search adapter (core/musicbrainz_search.py).
Covers the behavior changes from the search-overhaul PR:
- Artist search is re-enabled and score-filtered
- Bare name queries route through artist-first → browse
- Structured 'Artist - Title' queries stay on text search
- Top-artist resolution is memoized per instance
- Cover Art URLs are constructed, not probed
