Upstream Vorssaint updates

This PR tracks the original repository's main branch. New upstream commits
are added to this same PR by the daily Sync upstream workflow.

Before merging:

• Review changes alongside our volume indicator and panel customizations.
• Check the Upstream merge check status; it reports merge conflicts with main.
• Approve CI workflows if requested and review their results before merging.
• Resolve any merge conflicts and test the resulting app.
• Use Create a merge commit to preserve shared upstream history; avoid squash
  or rebase merging these sync PRs.

This automation does not merge the PR, rebuild the local app, or update your Mac.
