Verify that all execFileSync calls in engine.ts use { stdio: "pipe" }
to prevent subprocess output (uv, pip install, python --version, etc.)
from leaking into the TUI's text input area.
Tests use real subprocess calls via spawnSync to confirm the piping
behavior end-to-end, plus a source-level check that every call site
in engine.ts includes the stdio option.

Without this option, subprocess output from uv, pip install, tar, and python/uv --version leaks into the TUI's text input area. Piping stdio suppresses this noise while still capturing the return value. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Sorry, something went wrong.
With stdio: "pipe", e.message is a generic "Command failed" string. The actual diagnostics are in e.stderr, so prefer that for telemetry. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
