Adds modelSupportsReasoningEffort(modelId) helper to model-match.ts returning 'none' | 'binary' | 'levels'. buildDeepSeekRequest now dispatches on this helper instead of unconditionally writing reasoning_effort. Default mode is 'levels' when modelId is omitted, preserving existing DeepSeek behaviour bit-for-bit. Pre-empts the GLM-style regression seen upstream (anomalyco/opencode#32446) where a blanket id.includes() gate silently dropped variants when new model versions arrived. Closes #819 [alexi-bot]

Type of change
What does this PR do?
GLM-5.2 supports two thinking-effort levels (High and Max), but
ProviderTransform.variants()inpackages/opencode/src/provider/transform.tsreturns{}for any model whose ID contains"glm". This blanket exclusion was added for older GLM models that only have a binary thinking toggle, but it also suppresses GLM-5.2 which is different — Z.AI docs confirm it exposes High and Max effort levels.The fix carves out GLM-5.2 before the blanket exclusion so it returns
high/maxvariants. Earlier GLM models (5.1, 5, 4.x) still hit theid.includes("glm")check and correctly get{}since they only support a thinking toggle.Ref: https://docs.z.ai/devpack/latest-model
