Debug Holoscan CLI commands

Purpose

Turn one concrete CLI failure into a minimally fixed, reproducible passing command with focused regression proof.

Inputs

Required, from the user's report or the affected checkout:

• the affected user-provided holoscan-applications checkout or standalone Module repository;
• one exact failing, hanging, regressed, or semantically wrong holoscan command;
• expected and observed results, relevant inputs, and the point where progress stops;
• the runtime needed to reproduce the command.
