feat(provider): set temperature 1.0 for GLM-5.2

[phalla-doll]

Issue

Closes #32172

Summary

Z.AI just released GLM-5.2 — their latest reasoning model with a 1M context window. The model definition is being added to models.dev in anomalyco/models.dev#2275. Once merged there, opencode will pick it up automatically through the model catalog.

This PR adds the only opencode source change needed: setting temperature: 1.0 for GLM-5.2, consistent with GLM-4.6 and GLM-4.7. Z.AI docs recommend temperature: 1.0 for all reasoning models (see Deep Thinking docs).

What already works without changes

Concern	Why
Reasoning (thinking)	transform.ts auto-enables thinking: { type: "enabled" } for all zai/zhipuai provider IDs
Variants (effort)	GLM models return empty variants (toggle, reasoning always-on) — correct for the thinking.type: enabled/disabled API
Interleaved reasoning	Set via models.dev interleaved.field = "reasoning_content"
Model metadata	From models.dev PR #2275

Changes

• packages/opencode/src/provider/transform.ts: Add if (id.includes("glm-5.2")) return 1.0 in temperature()
• packages/opencode/test/provider/transform.test.ts: Add test block covering GLM-4.6, GLM-4.7, and GLM-5.2 temperature
