* refactor: replace super_clipboard with pasteboard, drop cargokit/Rust
super_clipboard pulled in super_native_extensions (a Rust native layer
built via cargokit), whose precompiled-binary download from GitHub
release assets has been intermittently failing the build ("Connection
closed while receiving data"). It was used for exactly one feature -
reading a clipboard image into the composer - in a single file; the
other 12 imports were dead.
- Swap super_clipboard -> pasteboard (platform-channel, no Rust).
- Rewrite readClipboardImageAsXFileInternal() on Pasteboard.image
(PNG bytes), collapsing three helpers into one.
- Remove 12 unused super_clipboard imports.
- Regenerated plugin registrants / lockfiles drop super_native_extensions.
Removes the Rust toolchain requirement and the flaky download entirely.
Text copy/paste already used Flutter's built-in Clipboard and is
unaffected.
