Adds a parallel ThumbHash placeholder everywhere BlurHash is already used.
Remote events now carry both hashes; renderers prefer thumbhash when
available and fall back to blurhash. The MIP-04 `thumbhash` imeta field
that was previously reserved-but-unused is now wired end-to-end.
- New ThumbHash encoder/decoder in commons/commonMain (no new Gradle dep)
- New ThumbhashTag and thumbhash accessors/builders across NIP-17, 68,
71, 94, 95, 99, the experimental profile gallery, and MIP-04
- RichTextParser + MediaContentModels carry a thumbhash field alongside
blurhash so every downstream composable can pick its preferred placeholder
- New ThumbHashFetcher (Android + Desktop) registered with Coil, plus a
small placeholderModel(thumbhash, blurhash) helper centralising the
"prefer thumbhash, fall back to blurhash" rule
- Rename BlurhashMetadataCalculator -> PreviewMetadataCalculator; the
calculator decodes the bitmap / video thumbnail once and runs both
encoders on the same pixels to keep upload cost flat
- DesktopMediaMetadata, MediaUploadResult, and FileHeader now surface
both hashes through the NIP-96, Blossom, NIP-95, MIP-04, NIP-17 DM,
Classifieds, picture, video, and long-form upload paths
- Round-trip unit test for the ThumbHash port
Persist dismissed game IDs locally (SharedPreferences on Android,
java.util.prefs on Desktop) so completed games can be permanently
hidden from the chess lobby. Adds per-game dismiss button and
"Clear all" action when 2+ finished games exist.

- Create PlatformImage expect/actual abstracting Bitmap/BufferedImage
- Move pure blurhash algorithms (Base83, SRGB, CosineCache, BlurHashEncoder) to commonMain
- Rewrite BlurHashDecoder to return PlatformImage instead of Bitmap
- Add PlatformImage.toBlurhash() extension in commonMain
- Add platform-specific Bitmap.toBlurhash() and BufferedImage.toBlurhash()
- Add base64Image toPlatformImage() for both Android and JVM
