Add task ledger (TASKS.md) parsing and stale-task archival for maintaining
agent task state across context compactions. Post-compaction recovery injects
memory_recall + TASKS.md read steps after auto-compaction. Sleep cycle gains
entity dedup (Phase 1d) and credential scanning. Memory flush now extracts
active task checkpoints. Compaction instructions prioritize active tasks.
