A failed download has no usable output file, so error notifications now
carry no buttons at all; only the done event offers open file / open
folder actions.
Terminal task notifications now carry actionable buttons and respond to
clicks instead of being inert:
- Done notifications offer Open File and Open Folder for single-file
tasks, and Open Folder only for folder tasks (e.g. multi-file
torrents), following the same rule as the task details page. Error
notifications offer Open Folder only, since the output is rarely
usable.
- Clicking the notification body brings the app window back to the
front (show + focus), covering the close-to-tray case.
- The click target is snapshotted into the notification (Windows: action
arguments; macOS/Linux: notification payload) so buttons keep working
after the task record is deleted, and a missing file is logged instead
of surfacing an OS error dialog.
- macOS resolves buttons through three pre-registered notification
categories (done single-file / done folder / error); Windows uses the
actions API of the pinned notification plugin fork; Linux uses
freedesktop notification actions.
- New openFolder label localized in all 22 ARB catalogs.
Cold-start activation is intentionally out of scope: when the process is
not running, OS activation opens the main window without dispatching the
button action.
