Subject: [PATCH] fix(opencode): use openai-compatible SDK for e2e LLM mock
 routing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The e2eURL() path used createOpenAI().responses() which produces a
Responses API format that the mock server's SSE stream can't correctly
convey tool calls through. Switch to createOpenAICompatible().chatModel()
which uses the chat completions format — matching what the mock was
designed for and what the integration tests use.

This only affects the OPENCODE_E2E_LLM_URL code path (e2e tests only).
