SDK v0.0.79

• The hub's durable event log is now capped at 64 MiB on disk. Event envelopes carrying full session snapshots could previously accumulate to tens of gigabytes, since row and time retention alone did not bound file size and deletes never shrink a SQLite file. Oldest events are dropped first and the file is vacuumed to return the space, and pruning now also runs after every 16 MiB appended instead of waiting for the hourly sweep
• Fixed task.completed telemetry being dropped for most interactive sessions. The event is now emitted from every session teardown path, exactly once per session
• Refreshed the model catalog. Adds two providers (AgentRouter and Opper) and updates model lists and pricing across providers. The resolved default model changes for Aki.io and NanoGPT, so if you use one of those without pinning a model you will get a different default
