evict
suspend fun evictTiles(content: GpkgContent, policy: CachePolicy): ERROR CLASS: Unresolved name: withContext
Evict image/elevation/vector tiles per policy. Capacity-only: CachePolicy.staleAfter never deletes (stale tiles refresh in place via SWR). CachePolicy.maxEntries (row count) drops oldest-inserted rows first (by id, the autoincrement PK), one row per tile so a tile is never split. No-op when read-only or unbounded.
