OpenClaw adds self-updating model catalog so new models work without an app update

OpenClaw rebuilt how it discovers models so new ones like GPT-6.1 Sol appear without shipping a release, pulling lists from a self-updating catalog at catalog.openclaw.ai (rebuilt every four hours, about 1,000 models), each account's own provider model list, and a handshake with a newer Codex on your PATH. The catalog switches live on a running Gateway, and model lists no longer shrink after provider timeouts or catalog swaps.
