- uses textContent field for standard.site records (no block parsing needed)
- falls back to leaflet block parsing for pub.leaflet.* records
- detects platform from content.$type prefix (leaflet, pckt, offprint)
- ExtractedDocument owns allocated memory, has deinit() method
- explicit error types (Allocator.Error) for all internal functions
- uses @tagName for Platform.name()
- StaticStringMap for plaintext block types
- indexer now stores platform and source_collection
- removed inline extraction code from tap.zig (~100 lines)
