Fix: Use full path for phparkitect command

The PATH environment variable modification wasn't working correctly
in the entrypoint context. Reverting to use explicit full path
/composer/vendor/bin/phparkitect to ensure the command is found.

This fixes the test failures where phparkitect command was not found.
