"""Add respawn_tracker.revisit_resets — persist the revisit-reset counter.

Mirrors tracing_resets: the PM-respawn breaker's revisit_resets is kept in
memory only and reset to 0 on restart, re-burning the counter. Persist it so a
restart preserves the count. Additive column with default 0; no data change.
