Huang Xin 7185dca1a2 feat(reader): add save/share button to image gallery toolbar (#4680)
* feat(reader): add save/share button to image gallery toolbar

Add a button to the top-right toolbar of the fullscreen image viewer
that saves the currently viewed image to the device. It uses the native
or web Share flow where available (iOS/Android/macOS, navigator.share)
and falls back to a save dialog or browser download otherwise, reusing
the existing export path via appService.saveFile.

The button icon and label reflect the active flow (share vs save).
Adds dataUrlToBytes/imageExtensionFromMime helpers, unit and component
tests, and translations for the new strings across all locales.

* fix(share): write shareable file to a Temp subdirectory to avoid 0-byte share

On Android, Tauri's Temp dir is the app cache dir, and the sharekit plugin
copies the shared file to <cacheDir>/<name> before firing the share intent.
When saveFile wrote the shareable file to the Temp root, that copy became a
copy onto itself whose output stream truncated the source to 0 bytes, so the
shared image (and any shared export) arrived as a 0 KB file. Write the file
to a Temp subdirectory instead so the plugin's copy has a distinct source.

Verified on a Xiaomi device: sharing a file in the Temp root truncated it to
0 bytes, while sharing from the subdirectory produced a real, non-empty copy.

* feat(reader): save image to system gallery on Android

The Android share sheet cannot save an image to a file (no file manager
registers as an ACTION_SEND target), so the Save Image button now writes
the image straight into the system photo gallery via MediaStore. It lands
in Pictures/Readest, visible in Gallery and the Files app, with no picker
and no storage permission on Android 10+.

Adds a save_image_to_gallery command to the native-bridge plugin (Rust +
Kotlin MediaStore insert) and an appService.saveImageToGallery method. On
Android the Save button uses it; iOS/macOS/desktop/web keep the existing
share/export flow, and the button label/icon reflect the actual action.

Also includes local agent memory notes that were staged alongside.
