* Add lightweight event loop watchdog monitoring
- Thread-based watchdog detects event loop hangs >15s
- Runs independently, won't interfere with normal operation
- Disabled in test environments
- Minimal overhead, just heartbeat checks every 5s
* actually test it
* Add test script to validate watchdog detects hangs
Run with: uv run python test_watchdog_hang.py
Tests:
- Normal operation (no false positives)
- Short blocks under threshold (no alerts)
- Long blocks over threshold (correctly alerts)
Change the Fern docs custom domain from docs.letta.com to docs-legacy.letta.com.
Next steps:
- Contact Fern to receive new CNAME and TXT records
- Update DNS records for docs-legacy subdomain
- Wait for SSL provisioning

* Add Letta Cloud-only warning to SDK v1.0 migration guide
Added prominent warning at the top of the SDK v1.0 migration guide to clarify that:
- SDK v1.0 is only supported on Letta Cloud
- Self-hosted Letta v0.13.x does NOT support SDK v1.0
- Users should continue using SDK v0.x with self-hosted until future releases
This prevents confusion for self-hosted users trying to upgrade to SDK v1.0.
