Add a local smoke-test helper for Perl dependencies

[ap0ught]

Summary

Add a small local smoke-test helper so the Perl app can be verified consistently after dependency setup.

Why

I had to install Term::Animation and Curses manually to run the app locally, and the verification steps are easy to forget or mis-type.

Proposal

• Add a repo-local smoke-test script
• Have it check the required Perl modules
• Compile both executable scripts with perl -c
• Print a clear message when the environment is missing the needed Perl libs

Acceptance Criteria

• One command is enough to validate the local Perl setup
• The helper works with a user-local CPAN install
• The script fails clearly when dependencies are missing
