Summary
Clicking a PDF attachment now opens the in-app preview modal (same as images and text), instead of triggering an immediate browser download or opening an external viewer on desktop.
Changes
*.pdffiles with empty,application/octet-stream, orbinary/octet-streamMIME are treated as PDFs so the attachment row uses "preview" instead of "download only" (which previously led to Save As on Tauri or a forced download in the browser).<object>pointed at ablob:URL built from decoded attachment bytes; the blob URL is revoked when switching attachments or closing the modal.open_file_with_systemRust command andopenWithSystemViewerbridge helper. Explicit download still uses Save As (save_file_with_dialog) or the browser download control.URL.createObjectURL/revokeObjectURL; unit tests cover MIME/filename PDF detection and Tauri opening the modal for PDFs.AGENTS.mdupdated to match the above.Verification
