perf(agent): use HashSet for eviction ID membership checks in consolidation

Browse Source 
records.retain(|r| !evict_ids.contains(&r.id)) called Vec::contains
(linear scan) for every record against evict_ids, giving O(n·m) cost
on both Working- and Episodic-tier eviction every consolidation tick.
Build evict_ids as a HashSet for O(1) membership checks.
