Subject: [PATCH] fix(pi-local): parse models from stderr

Pi outputs the model list to stderr instead of stdout. This fix checks
stderr first and falls back to stdout for compatibility with older
versions.

Fixes model discovery returning empty arrays and environment tests
failing with 'Pi returned no models' error.
