Craft parts swallows chisel errors if logging level is info or higher

Current evaluation

Chisel slice failures still lose command output at INFO or higher because the error stream is captured through logger.debug; the triaged bug remains reproducible.

Suggested action: keep open

Reason: The current chisel.py passes logger.debug to os_utils.process_run and builds ChiselError from the resulting debug-only stream, so INFO-or-higher logging leaves details empty. The issue is labeled Status: Triaged and Type: Bug, and existing integration tests force DEBUG logging, so a focused fix and regression test remain warranted.
