* feat: add opt-in task notes and compacted history recall * fix: validate task continuity state and preserve user answers Honor explicit opt-out, preserve clarification replies and capture failure statuses, validate notebook writes, and clear branch archive references. Update the config version and audit optional LLM credentials, with regression and integration evidence. * fix: align Helm config version with task continuity schema * fix: preserve mixed task history and declare continuity policies * fix: recover malformed history and evict archives atomically
