Code Review
This pull request correctly addresses the findings from the previous review. The addition of the EXIT trap provides a robust safety net for cleaning up temporary files, and removing the output redirection from the brew uninstall command improves error visibility. I have one suggestion regarding the file cleanup mechanism to ensure it aligns with the established project pattern for robustness and consistency.

Appending to the _SCAN_CLEANUP_FILES array as suggested is a good practice for robustly managing cleanup lists, ensuring that registered files are not lost. However, for resource cleanup in shell scripts, the established project pattern is to use _save_cleanup_scope, trap '_run_cleanups' RETURN, and push_cleanup. Please ensure that this _SCAN_CLEANUP_FILES mechanism is either integrated into or replaced by the push_cleanup pattern for consistency and comprehensive cleanup on all exit paths.

| _SCAN_CLEANUP_FILES+=("$migratable_file" "$non_migratable_file") |
References
- For resource cleanup in shell scripts, use the established project pattern: use
_save_cleanup_scope,trap '_run_cleanups' RETURN, andpush_cleanupfor robust cleanup on any exit path, and also include explicit manual cleanup at the end of the normal execution path as a 'fast-path'.

Applied in follow-up PR #4406. Changed _SCAN_CLEANUP_FILES=(...) to _SCAN_CLEANUP_FILES+=(...) — the append operator is the correct pattern for a registry-style array and prevents silent overwrites if the array is ever populated from multiple call sites.

Summary
Fixes high-severity findings from PR #1184 review feedback (issue #3525).
Changes
_SCAN_CLEANUP_FILES=()array andEXITtrap at script top to guarantee temp file cleanup on unexpected script termination. The existing_save_cleanup_scope/push_cleanupRETURN trap (from coderabbit's fix) handles normal function exit; the new EXIT trap provides a safety net for signals andset -eaborts before the RETURN trap fires.2>&1 | tail -3from thebrew uninstallcall incmd_migrate. This was suppressing stderr from brew, making failures hard to diagnose. Since the call is inside anifstatement, errors now print to stderr without causing the script to exit.Findings addressed
