Description

Large Vec allocation on every trigger check — Lines 145-151 and 235-241 allocate new Vec<Uuid> to collect routine IDs before batch query, even when cache is empty. Called on every message in agent loop.

Fix incoming — adding early-return when cache has no matching matchers before collecting IDs into Vec.
