PodcastSeries JSON-LD is missing sameAs/logo, and Organization sub-nodes have no contactPoint/address

Inizia in packages/starpod/src/layouts/Layout.astro e analizza come vengono assemblati i nodi PodcastSeries e Organization annidati. Poi leggi StarpodConfig e i relativi dati platforms, oltre alla issue #69 relativa alla fonte di contatto proposta. Il lavoro è completo quando sameAs viene valorizzato a partire dagli URL delle piattaforme disponibili, i logo di Organization sono supportati e l’ambito di contactPoint/address è definito e riflesso nei dati strutturati.

Context

An is-agentic.com scan of whiskey.fm flagged incomplete structured data:

JSON-LD Organization with name + description - add url and sameAs/logo/address for full score

Organization schema found but missing: contactPoint, address
Add Organization JSON-LD that includes both contactPoint (with email/phone and contactType) and address (PostalAddress). This lets AI verify your business legitimacy and answer contact queries.

Current state

packages/starpod/src/layouts/Layout.astro already emits a solid PodcastSeries node (name, about, description, url, webFeed, image, nested author/publisher Organization objects) — good baseline. What's missing:

{
  '@context': 'https://schema.org',
  '@type': 'PodcastSeries',
  // ...
  author: { '@type': 'Organization', name: show.title, url: canonicalURL.origin },
  publisher: { '@type': 'Organization', name: show.title, url: canonicalURL.origin }
  // no sameAs, no logo on the PodcastSeries node
  // no contactPoint/address on the Organization nodes
}

• No sameAs array on the PodcastSeries node — starpodConfig.platforms already has apple/spotify/youtube/overcast/pocketCasts URLs, which are exactly what sameAs wants (canonical profile links proving the entity is the same across the web). This looks like a straightforward win since the data already exists in config.
• No logo on the Organization sub-nodes (only the top-level PodcastSeries.image is set).
• No contactPoint (email + contactType) or address on the Organization nodes — reasonable, since StarpodConfig has no field for either today. address may not even make sense for every show (a podcast isn't always a registered local business) — could be optional/skippable, but contactPoint seems like a reasonable ask once contact-page work (#69) lands, since that's the same email/contact info.

Proposed fix

• Populate sameAs on the PodcastSeries node from Object.values(starpodConfig.platforms).filter(Boolean).
• Add an optional logo field to StarpodConfig (or reuse an existing show-image asset) and wire it onto the Organization nodes.
• Add an optional contactPoint (built from a config-level contact email, see #69) once there's a canonical place to source it from. Treat address as optional/skippable — not every show has one worth publishing.
