Foundation for making CCIP character references a precomputed, INCREMENTAL artifact instead of a request-path rebuild (kills the per-accept ~4s suggestions stall; cost will scale with change, not library size): - character_prototype: a character's reference CCIP vectors, capped to MLSettings.ccip_prototype_cap so match cost doesn't grow with popularity. - ccip_prototype_state: per-character fingerprint (ref count + max region id) + updated_at → drives per-character incremental rebuilds and the matcher cache's reload-only-what-advanced. - MLSettings.ccip_ref_signature (cheap global change gate) + ccip_prototype_cap. Migration 0079. Schema + models only — the builder service, refresh task/beat, and matcher rewrite land in the following steps.
