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 with MEM0_TELEMETRY=false (#7110)
