/**
 * Fires when the site owner uninstalls TruePlayer from Plugins → Delete.
 *
 * The free plugin owns no custom tables (Pro installs its own schema and is
 * responsible for dropping it on its own uninstall). This cleanup removes the
 * plugin's options, transients and generated poster attachments. Legacy option
 * names (`trueplayer_db_version`, `trueplayer_first_install_time`) that older
 * versions wrote are still deleted here so upgraders don't leave orphans.
 *
 * Honours the Settings → "Keep data on uninstall" switch (option
 * `trueplayer_keep_data_on_uninstall`). On a multisite network uninstall, runs
 * per site via `get_sites()` so no site is skipped.
