Improve user switching in Docker execution

[imsudiproy]

Refactor user switching logic for container execution.

Summary by CodeRabbit

• Chores
  • Improved verification reliability by adding container user awareness: the process now ensures scripts run under the expected user, switching when needed.
  • Added error handling for undetermined container user, with cleanup and exit on failure.
  • Maintains existing log capture, finalization, and path-based script invocation while reducing unnecessary user switching.

Walkthrough

Adds container-user detection to auto_verify.sh: the script queries the current user inside the container, handles failures, and only switches to the "test" user with su when the container user differs; otherwise it runs the build script directly, preserving existing logging and cleanup flows.

Changes

Cohort / File(s)	Summary
Container user detection & execution flow auto_verify.sh	Query container user; on query error perform cleanup and exit; if user != test switch to test via su before running the build script, otherwise execute build directly; maintain existing log capture and finalization.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Inspect the user-query command and its error handling
• Verify su invocation and quoting/escaping when running the build script
• Confirm log capture, cleanup and exit-code propagation remain correct

Poem

🐰 I peeked inside the container den,
"Who's running this?" I asked again.
If it's already test, I clap and cheer,
Else I nudge it gently — "switch, please" — and steer.
Logs tucked in my satchel, I hop away, sincere.
