Shelf v0.4.6

Shelf v0.4.6

Shelf v0.4.6 fixes a beta update download failure and adds live download
progress for self-update.

Changes

• Beta update download reliability:

  • Fixes update download is not linked to a verified manifest, which fired
    whenever two update checks overlapped (for example the auto-update notice
    firing while the Settings panel ran its own check). A re-fetch of the
    manifest no longer invalidates the download token the renderer is holding.

• Download progress and cancellation:

  • Self-update downloads now show a live progress bar with transfer rate and
    estimated time remaining.
  • In-progress downloads can be cancelled; the verified token is preserved so
    a retry does not require re-checking for updates.

Tester Notes

Open the Settings → Updates panel and trigger a beta update check, then open
another surface that runs an update check at roughly the same time. Confirm the
download still starts and completes without the "not linked to a verified
manifest" error, and that the progress bar and cancel button behave correctly.
