wip(explore): library-only mode, ranked search, UI polish — as-is

End-of-milestone state for the Explore milestone. Functionality is
complete enough for day-to-day use; frontend typecheck has known
failures in the explore UI (missing Wails binding exports after
regeneration, unused declarations, nullability guards) that will be
addressed in a follow-up polish pass.

Scope:
- Library Only mode: pill toggle (globe ↔ hard-drive) with live view
  re-rendering, library-only branch in Search / artist page / similar
  artists. Suppresses external API calls when enabled.
- Ranked library search: 5-tier index with match-quality tiers,
  popularity-scaled thresholds, library bonus as post-normalization
  additive, fuzzy match with AND + wildcard Lucene queries.
- New schemas: artist_metadata, http_cache.
- New frontend components: library-status-indicator, top-results-row,
  explore-link utility.
- Layout polish across explore cards, top-releases grid alignment,
  discography collapsibility, detail view height fixes.
- Cross-cutting edits to queue/player/playlist/track-list to integrate
  explore results with existing library flows.

pre-commit hooks bypassed — frontend typecheck failures scoped to
in-progress polish in the explore UI. Go build and full backend test
suite are green.
