Adds search_discogs for catalog-wide queries beyond your own collection, plus two real-world accuracy fixes: owned-marker correctness across pressings, and exact genre/style matching.

What’s new

• search_discogs tool — search the full Discogs catalog, not just your collection. Default type is master so album lookups don’t return duplicate pressings. Results get a ✓ marker when you already own them.
• Tool lists in README, marketing page, auth_status, and server_info refreshed with grouped categories (Search, Collection, Folders, Custom Fields, Diagnostics).

Fixes

• Exact genre/style matching (#17) — substring matching caused music to match Non-Music, flipping the filter to OR mode and returning unrelated releases. Now uses exact equality per release.
• Release-result owned-marker is now strict on release.id. Previously, owning one pressing of an album marked every other pressing as owned too, because isOwned() matched on master_id first. Caught by real-world dogfood on “Christian Scott Stretch Music”.

Under the hood

• Root CLAUDE.md for Claude Code auto-discovery; removed stale development/CLAUDE.md.
• GitHub release workflow auto-cross-posts to elezea.com.
