Cerebras (docs/providers/cerebras.md): rewrote against
extensions/cerebras/openclaw.plugin.json. Added a complete properties
summary, CodeGroup for onboarding/direct-flag/env, a Reasoning column on
the four-model catalog table (Z.ai GLM 4.7 and GPT OSS 120B are
reasoning-capable; Qwen 3 235B and Llama 3.1 8B are not), and a
CardGroup of related links.
Groq (docs/providers/groq.md): expanded the catalog from 4 hand-picked
entries to all 18 bundled models from extensions/groq/openclaw.plugin.json
with model refs, reasoning flags, input modalities, and context windows.
Removed a stale 'Mixtral 8x7B' row that does not exist in the bundled
catalog. Surfaced the audio media-understanding contract (whisper-large-v3-turbo,
auto priority 20) as a properties table and explained the per-model
reasoning_effort mapping for qwen/qwen3-32b vs the GPT OSS reasoning
models. Added an onboarding CodeGroup so the API-key step does not skip
'openclaw onboard --auth-choice groq-api-key'.
SGLang (docs/providers/sglang.md): added a properties summary table at
the top, including the Qwen/Qwen3-8B model placeholder from
extensions/sglang/defaults.ts, the supportsStreamingUsage runtime flag,
and the modelPricing.external: false setting. Clarified that the
onboarding choice id is bare 'sglang' (custom method) rather than the
'-api-key' suffix used by other providers, matching the manifest.
