Hosts the wp-admin Podcast experience for the Jetpack plugin (Simple and Atomic only).
The package is gated behind the jetpack_podcast_untangle filter (default off). Until the filter is flipped on, the package contributes nothing — the legacy podcasting code (Automattic_Podcasting in the wpcom mu-plugin and the at-pressable-podcasting bridge plugin) keeps running unchanged. Subsequent PRs in the untangle train layer the new wp-admin SPA, REST integration, and feed customization on top of this gate.
