feat(wafer/kimi-k3-fast): add new models [bot]

[models-bot]

Auto-generated by model-addition-agent for wafer/kimi-k3-fast.

Note

Low Risk
Metadata-only YAML addition with no runtime or routing logic changes.

Overview
Adds a new Wafer provider definition for kimi-k3-fast, registering it as an active serverless chat model sourced from Wafer’s models API.

The entry documents 1M-token context, text + image input, thinking support, and modes chat and responses, with features including function calling, structured/JSON output, and per-token pricing (including cache-read input cost).
