Note

Medium Risk
Touches untrusted wallet short-sync cache eviction logic; an off-by-one here can affect whether coin states are re-applied or dropped around reorg boundaries.

Overview
Fixes an off-by-one in untrusted close-to-peak syncing by changing cleanup_race_cache() to retain entries starting at backtrack_fork_height + 1 after applying per-height race-cache updates, instead of including the fork height itself.
