Stops unbounded growth of patterns.rvf / brain.rvf.
- #495: AbortSignal in HybridMemoryBackend.initialize() so a 5s
createHybridBackendWithTimeout abort actually cancels the work
instead of leaking a 14-min runaway init (~20 GB / 12 MB/s leak
observed in the field). UnifiedMemoryManager.initialize() also
accepts {signal} with throwIfAborted() at each await seam.
- Post-dream compaction in DreamScheduler — threshold-gated compact()
against patterns.rvf and brain.rvf so append-only growth has a
steady-state janitor.
- Boot-time size guard in getSharedRvfAdapter() for one-shot recovery
of installations already in the bad state.
- Bounded SQLite→RVF backfill (top-1000 by last_used_at) so
`: > patterns.rvf` for disk recovery doesn't trigger an unbounded
replay (the "regrew to 59 GB" pathology).
- RvfDualWriter.compact() for brain.rvf parity.
Three operator env knobs added (no rebuild needed):
- AQE_RVF_SIZE_GUARD_BYTES (default 256 MB)
- AQE_RVF_DEAD_RATIO_THRESHOLD (default 0.30)
- AQE_RVF_BACKFILL_LIMIT (default 1000)
29 new unit tests. Performance gate 15/15 pass. test:ci 4035 pass
(3 pre-existing failures, verified identical on main).
