Subject: [PATCH] chore(2meet-data-optimizer): prefix the global variables in
 uninstall.php

- $bootstrap_files, $bootstrap_ok, $f, $result, $snapshot_id and $dir become
  $wpdo_* like the file's other globals (WordPress.org Plugin Check)
- Verify: PrefixAllGlobals sniff 0, phpcs, UninstallGuardTest and
  InstallerCleanupTest, unit 701
- PR: PR-098
