feat: add ExtractFn utility, cursor agent workspace from thread context

Browse Source 
- New ExtractFn = <T>(schema, prompt) => (ctx) => Promise<T>
- createExtract(provider) creates an LLM-backed ExtractFn
- CursorAgent removes workdir config, uses ExtractFn to resolve workspace from ThreadContext at runtime
- buildAgentPrompt(ctx) — reads systemPrompt from ctx.currentRole
