FN-5941: stop todo/in-progress flapping
Prevent scheduler and self-healing churn from bouncing live tasks between todo and in-progress.
- add dispatch oscillation settings, scheduler settle-window tracking, and auto-pause audit/logging for rapid todo↔in-progress cycles
- harden self-healing against reclaiming genuinely active tasks by checking executor activity, grace windows, and heartbeat runs before requeueing
- cover the new reliability invariants with focused engine tests and document the new diagnostics/settings behavior
