Gplay Submission Checks

This is the pre-flight checklist you run before hitting submit to Google Play. It walks through bundle validation, metadata limits (30 char titles, 80 char short descriptions), screenshot requirements, version code conflicts, and the data safety form that trips up half of all submissions. The dry run command is especially useful since it validates everything server-side without actually committing the release. Also covers the usual rejection culprits like targeting old API levels, missing phone screenshots, and signing key mismatches. If you've ever had a release rejected for something you could have caught locally, this is that systematic runthrough you wish you'd done.
