feat(node): add type definitions for all namespaces

Phase 2: Node.js Type Definitions

New types (13 total):
- GeoLocation (geoType, coordinates, crs)
- MediaThumbnail (url, width, height)
- MediaContent (url, type, filesize, width, height, duration)
- ItunesFeedMeta (author, owner, categories, explicit, image, keywords, podcastType, complete, newFeedUrl)
- ItunesOwner (name, email)
- ItunesCategory (text, subcategory)
- PodcastMeta (transcripts, funding, persons, guid, value)
- PodcastFunding (url, message)
- PodcastEntryMeta (transcript, chapters, soundbite, person)
- PodcastChapters (url, type)
- PodcastSoundbite (startTime, duration, title)
- PodcastValue (type, method, suggested, recipients)
- PodcastValueRecipient (name, type, address, split, fee)

Security: SSRF warnings on all URL fields
