Description

As of 1.2.25 I'm getting a lot more timeouts on larger context sessions with local models like 1.2.25. With default settings I got an error after 2 minutes of prompt processing on a 100k context session of SSE read timed out.

After adjusting timeouts in opencode.json to 300,000 milliseconds it improved but doing a compaction still generated a less descriptive timeout of TimeoutError: The operation timed out after 5 minutes.

I've set it to

    "lmstudio": {
      ...
      "options": {
        ...
        "timeout": 3000000,
        "chunkTimeout": 3000000
      },

Which is 50 minutes which has resolved it for now. I couldn't see an obvious specific timeout in the diff between 1.2.24 and 1.2.25, but it's definitely more aggressive now and started occuring with a silent update.

Steps to reproduce

1. Open a session with a long context (100k-ish)
2. Choose a local model like Qwen3.5 27b that is somewhat slow on your system
3. Run /compact
4. Experience timeouts
