The gbrain import (the long pole on big brains) had a hardcoded 30-min timeout,
so large memory corpora got SIGTERM'd mid-import on /sync-gbrain --full. Make it
configurable via GSTACK_INGEST_TIMEOUT_MS (default 30 min, validated 1min–24h).
gstack can't drive gbrain's internal resume, but the existing SIGTERM forwarder
already preserves gbrain's import-checkpoint.json, so the next run resumes. On a
timeout we now say so explicitly ('checkpoint preserved — re-run /sync-gbrain to
resume, raise GSTACK_INGEST_TIMEOUT_MS for big brains') instead of surfacing a
bare 'exited null'. True gstack-driven ingest-resume is deferred to gbrain
(.context/gbrain-asks.md).
Also guards the module's main() behind import.meta.main so resolveImportTimeoutMs
is unit-testable; the orchestrator runs it as a subprocess where main still fires.
New test/memory-ingest-timeout.test.ts pins default/override/invalid resolution.
