* feat(chat): full-screen image viewer (issue #723)
Tap any chat image (markdown , inline attachment thumbnail,
or bubble image) to open a full-screen viewer:
- pinch-zoom + pan via native detectTransformGestures
- downswipe-to-dismiss at min zoom
- Save -> device Downloads (MediaStore), Share -> Android share sheet
(both fully device-local; never sent back to the Hermes server)
Plumbing: onImageClick(ImageViewerModel) flows MarkdownText ->
ChatBubble/InlineAttachment -> ChatMessageList -> ChatScreen (state +
ImageViewerDialog). ImageBytesResolver reuses the existing authed
OkHttpProvider path for gateway http(s) sources; data:/content://
handled locally. No new dependencies.
Closes#723
* fix(chat): resolve strings at composable scope to satisfy LocalContextGetResourceValueCall lint
Lint forbids reading resource *values* from LocalContext.current inside
coroutine lambdas. Hoist all viewer strings via stringResource() at
composable scope and reuse them in onSave/onShare.
