Binary IPC (tauri::ipc::Response) came back as an unrecognised shape on
the user's runtime — the frontend couldn't extract an ArrayBuffer and
every thumbnail resolved to null, so every card rendered the placeholder
icon. Added:
- Widened the invoke typing to ArrayBuffer | Uint8Array | number[] so
all three known Tauri/WebView2 deserialisation shapes parse.
- A one-time console.warn when the Response body lands as an unknown
object shape, so the real wire format can be diagnosed if this ever
trips again.
- An automatic tier-2 fallback: if the binary path produced 0 usable
bytes, re-invoke the legacy base64 command and decode client-side.
Slower on the JS thread than binary IPC but known to work across all
Tauri 2.x runtimes.
Net behaviour: thumbnails render again. If the binary path works on a
given build, we get the fast path; otherwise the base64 fallback keeps
the picker usable.
