fix(FN-1256): auto-recover tasks with all steps done but no task_done call

Browse Source 
When context overflow or compaction causes an agent to lose awareness of
the task_done tool, the executor now checks if all steps are complete
before failing — treating it as an implicit task_done. Also adds
self-healing recovery for tasks that already slipped through as
misclassified failures in in-review.
