Add fixture support for tmpdir-backed mock server tests, extend the mock LLM server DSL for failure and hanging cases, and migrate the next prompt tests to the HTTP-backed path.
Default the shared effect test helper to support both test-clock and live execution, and switch the current opencode effect tests to the live path for real integration behavior.
- Replace Bun.serve with Effect HTTP server using NodeHttpServer
- Add TestLLMServer service for mock LLM testing with SSE responses
- Update prompt-provider.test.ts to use testEffect pattern with provideTmpdirInstance
- Remove redundant test/fixture/effect.ts (using existing test/lib/effect.ts instead)
