Pull request overview

This PR (TIKA-4733) tightens release/distribution handling for Tika 4.x artifacts and updates CLI messaging/docs to better reflect the “zip distribution with lib/” packaging model.

Changes:

• Drop the redundant -bin.tgz server distribution, standardizing on .zip.
• Prevent selected distribution zips from being attached/deployed to Maven Central (attach=false) and add release-staging checks to fail fast if expected dist artifacts are missing.
• Improve tika-app batch/async invocation behavior with a clearer error message and update CLI documentation/examples accordingly.
