obol-core 0.4.0

//! Provider-keyed usage normalizers. Each turns a provider's raw `usage`
//! object into token buckets. The agent dialects and the `obol` house dialect
//! share these so the per-provider accounting — the cache-bucket split, the
//! OpenAI cached-subtraction, the part naive summers get wrong — lives in one
//! place, not once per dialect.
