Server exited before becoming ready (1) when starting t1code

Bug Description

When running bunx @maria_rcks/t1code, the TUI interface starts but the backend server crashes immediately with:

Error: Server exited before becoming ready (1).
    at waitForServerPort (/private/tmp/bunx-501-@maria_rcks/t1code@latest/node_modules/@maria_rcks/t1code/dist/index.mjs:4140:50)
    at async startServerSupervisor (/private/tmp/bunx-501-@maria_rcks/t1code@latest/node_modules/@maria_rcks/t1code/dist/index.mjs:4259:8)
    at async <anonymous> (/private/tmp/bunx-501-@maria_rcks/t1code@latest/node_modules/@maria_rcks/t1code/dist/index.mjs:6515:14)

The TUI renders but becomes unresponsive because the server process it manages has exited.

Environment

• macOS (Darwin 25.4.0)
• Bun 1.3.5
• t1code v0.0.15

Steps to Reproduce

1. Set environment variables:

   export ANTHROPIC_API_KEY="<key>"
   export ANTHROPIC_BASE_URL="https://api.minimaxi.com/anthropic"
   export ANTHROPIC_MODEL="MiniMax-M2.7-highspeed"

2. Run bunx @maria_rcks/t1code
3. Observe: TUI appears but immediately shows the error

Additional Notes

• API key and model are valid (tested with curl, returns successful responses)
• The error occurs even with valid API credentials
• Port 3939/3940 appear available (no process conflict)
• The server supervisor seems to exit with code 1 before the server becomes ready

Expected Behavior

t1code should start the backend server successfully and connect to the configured LLM API.
