Crate embedcache_core 

Pure-Rust core for embedcache: a content-addressed embedding cache backed by an embedded redb KV store.

• Key. A 32-byte blake3 hash of (model_name, 0x00, text). The null separator prevents (model="a", text="bc") from colliding with (model="ab", text="c").
• Value. [u64 inserted_at_secs LE][u32 dim LE][dim x f32 LE].
• TTL. Optional. Evaluated on get; expired entries are returned as None and removed by purge_expired.
