[Vasilev Dmitrii (gHashTag)]

Summary

Adds support for z.ai (Zhipu AI) as a new LLM provider in BrowserOS. z.ai provides an OpenAI-compatible API for coding models including glm-4.6, glm-4.5, and glm-4.5-air.

Changes

Core Integration

• Shared schemas (packages/shared/src/schemas/llm.ts): Added ZAI to LLM_PROVIDERS enum
• External URLs (packages/shared/src/constants/urls.ts): Added ZAI_API endpoint (https://api.z.ai/api/coding/paas/v4)
• Server provider factory (apps/server/src/lib/clients/llm/provider.ts): createZaiModel via OpenAI-compatible client
• Agent provider factory (apps/server/src/agent/provider-factory.ts): createZaiFactory for agent runtime

UI Integration

• Provider templates (lib/llm-providers/providerTemplates.ts): z.ai template with default model glm-4.6, 200K context window, image support
• Provider types (lib/llm-providers/types.ts): Added 'zai' to ProviderType union
• Provider icons (lib/llm-providers/providerIcons.tsx): Maps zai to @lobehub/icons ZAI icon
• OpenClaw map (entrypoints/app/agents/openclaw-supported-providers.ts): z.ai registered as supported provider
• New provider dialog (entrypoints/app/ai-settings/NewProviderDialog.tsx): z.ai available in manual provider setup

Models & Data

• models-dev-data.json: Added z-ai provider key with models:
  • glm-4.6 (default)
  • glm-4.5
  • glm-4.5-air
• providerTemplates.ts: Maps provider id zai → models-dev key z-ai

Dev Fixes

• helpers.ts: VITE_BROWSEROS_SERVER_PORT fallback for getMcpPort
• background/index.ts: Removed sidePanel.setOptions({enabled:false}) blocking dev sidepanel
• web-ext.config.ts: Removed --disable-browseros-extensions flag
• ProviderTemplatesSection.tsx: Added safeguard to ensure z.ai always appears in Quick provider templates

Testing

• Production build succeeds (bun run build)
• zai strings confirmed in output chunks (12 occurrences)
• Provider template hotfix verified in minified output

Screenshots

N/A — UI visible in AI Settings → Quick provider templates

Checklist

• Code follows project conventions
• No breaking changes to existing providers
• All provider types updated (server + agent + UI)
• Models dev data includes z.ai models
