ECA 0.153.0

Store chats in per-chat cache files with a lazy-loaded index instead of one whole-workspace blob, fixing CPU spikes and slow startup as history grows; legacy caches migrate automatically. #557

Hooks db_cache_path now points at the workspace cache dir instead of db.transit.json; read-chat --db-cache-path accepts the dir or a legacy file. #557

Keep compact_chat in the tool schema across normal and compact requests, preserving prompt-cache prefixes while rejecting calls outside active compaction.

Provide token metrics for ollama provider. #567.
