New Features:
- Usage telemetry: Anonymous usage events (
strands.store.init,strands.store.search,strands.store.add,strands.store.add_messages) ride the Mem0 SDK's existing PostHog client, unsampled, with no new dependency. Events carry only counts, durations, booleans, and coarse failure kinds: never queries, memory text, message content, entity ids, metadata, or API keys. Opt out withMEM0_TELEMETRY=false(#7110)
