fix: clear dedup guard state on task reset

[marcusquinn]

Summary

• cmd_reset() in state.sh clears retries, error, session_id, etc. when resetting a task to queued, but did not clear last_failure_at or consecutive_failure_count
• This caused the dedup guard (check_dispatch_dedup_guard) to see stale failure counts and cancel tasks on their next dispatch attempt
• Root cause of t004.35 and t005.5 being falsely cancelled after manual re-queue

Fix

Added last_failure_at = NULL and consecutive_failure_count = 0 to the cmd_reset() UPDATE statement, matching what reset_failure_dedup_state() already does for successful completions.

Summary by CodeRabbit

• Bug Fixes
  • Task reset operations now properly clear failure tracking metadata, ensuring a fresh state when resuming previously failed tasks.

Walkthrough

The supervisor state script's task reset operation now clears failure tracking metadata during reset to queued state, resetting the failure timestamp and consecutive failure counter to their initial values.

Poem

When tasks must rise and try once more,
Fresh metadata clears what came before,
The slate is wiped, the counters fall,
A clean reset for one and all! 🔄
