feat(wafer/GLM-5.2): add new models [bot]

[models-bot]

Auto-generated by model-addition-agent for wafer/GLM-5.2.

---

Note

Low Risk
Adds static provider metadata only; no runtime, auth, or application logic changes.

Overview
Adds a new Wafer provider definition for GLM-5.2, registering it as an active serverless chat model sourced from Wafer’s models API.

The entry sets per-token pricing (including cache-read), a 1M context window, text-only I/O, thinking enabled, and capabilities such as function calling, tool choice, structured/JSON output, prompt caching, and system messages, with chat and responses supported modes.

Gateway test setup failed for wafer

The test job aborted before any tests ran. Error:

Failed to apply virtual-account 'gateway-tester-v2-c0400cb2-4': {"statusCode":500,"message":"Error applying the manifest of type virtual-account"}

This is usually a transient infra issue (catalogue build, TrueFoundry API, GitHub archive). Try /test-models again, or check the job logs.
