• feat: unify build metadata and update deviceDisplayName for Tauri builds #1268
• ▶ feat: add desktop auto-update polling, pill status button, manual check for updates, move updater to AppShell #1235 (2 commits) ◀
• feat: add mise support and other goodies #1202

Description

• Adds a pill button on tauri desktop app that uses custom titlebar, I made SyncConnectionStatus.tsx component more generic, so it can be reused and so im using the same styling as SyncStatus pill.
• Adds auto-update polling (every 5 minutes), previously only updates were checked at startup.
• Updates are now auto downloaded in the background (in-memory), to be more instant.
• Added a manual check for updates button in Settings > About > Check for Updates
• Moved DesktopUpdater, WebUpdater and GlobalBannerRenderer all into Appshell.tsx so it runs and shows up on all pages, including auth. To avoid deadlocks if we break anything on some of the pages. previously if we broke auth for example, you could not push a update to auto updating apps to patch it. Now you can.
• update.body is now shown in the update Banner, it would be good for changelogs and such, depends if we populate it in the manifest.

Current auto-update flow is now:

• Custom Titlebar: Check for update on startup or via polling > show pill update downloading > show pill update available > click on pill > show update banner
• Native: Check for update on startup or via polling > show update banner
• Manual check: Click on check button > show no update available with timestamp of last checked OR show update banner if update available

Oh forgot to mention MacOS Titlebar is untested as I dont have an apple machine. so I think it should be good? but I'm not sure, the offset was a guess.
