v1.0.0
First stable release. All 10 tools (enrich_csv, lookup_card, resolve_card, search_cards, find_song_synergies, filter_collection, audit_csv, analyze_deck, what_am_i_missing, build_deck) have been in active daily use managing a real collection since v0.1.0, backed by a 278-test suite that runs in CI on Python 3.11–3.13 for every PR. Development Status moves from Alpha to Production/Stable to match.
Also rewrites tool docstrings across the board (search_cards, filter_collection, audit_csv, lookup_card, enrich_csv, analyze_deck, what_am_i_missing, find_song_synergies) to address low Behavior/Usage Guidelines scores from Glama's per-tool quality grading — each now states what's fetched live vs. cached, silent edge-case behavior, required input formats, and when to reach for it over a similar sibling tool.
No functional or breaking changes.
