Universal: install and auto-start ttyd on port 3010 (Dockerfile + CodeSandbox tasks)

[lordspline]

Summary

• Install ttyd (static linux x86_64) in universal devcontainer image
• Auto-start ttyd on port 3010 via CodeSandbox tasks so terminal is always available at https://{instanceId}-3010.csb.app
• Keep existing FastAPI (port 8000) and code-server (port 8080) tasks intact

Details

• .devcontainer/Dockerfile: curl ttyd v1.7.7 static binary to /usr/local/bin/ttyd and chmod +x
• .codesandbox/tasks.json: add a new task to run "/usr/local/bin/ttyd -p 3010 bash" with runAtStart: true and preview port 3010

Why

• Provide an interactive terminal per jam without modifying FastAPI runtime; CodeSandbox exposes port 3010 automatically when listening.

Notes / TODO

• No auth in V1; UI is gated in Scout; add TODO for auth and ARM64 in follow-up.
