- Add migration 021: recipe_browser_fts FTS5 table on category + keywords
columns, eliminating LIKE '%keyword%' full sequential scans on 3.1M rows
- _count_recipes_for_keywords now uses FTS5 MATCH (O(log N) vs O(N))
- browse_recipes reuses cached count, eliminating the second COUNT(*) scan
per page request; ORDER BY r.id replaces the unindexed ORDER BY title sort
- Module-level _COUNT_CACHE keyed by (db_path, keywords) means domain-switch
category counts are computed once per process lifetime
feat(find): dietary preset grid, Big 9 allergen pills, Hard Day Mode surface
- Dietary constraints replaced with toggle-button preset grid (8 options)
+ free-text "Other" field; removes dense freeform text input
- Allergies replaced with Big 9 pill picker (peanuts, tree nuts, shellfish,
fish, milk, eggs, wheat, soy, sesame) + "Other" for custom entries
- Hard Day Mode surfaced as a standalone aria-pressed button above the
dietary collapsible; no longer buried inside a collapsed section
- Active-state dot indicators on both collapsibles show filter engagement
at a glance without expanding
