User-report (mobilism): scenes are often poorly titled, so saved keyword queries are a useful extra retrieval strategy. New saved_searches table (device-scoped via X-Device-Id, unique per device+query, 50/device cap) + GET/POST/DELETE /saved-searches. Migration 0024. Verified CRUD on prod: add trims+dedups idempotently, empty rejected 422, delete idempotent. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
