Budgebell v0.3.0

Added

• Linux: pause nudges while you're away (idle), on a call (microphone in use), or in GNOME Do Not Disturb.
• Settings has an Updates section: it shows the running version, checks GitHub for a newer release, and installs it and restarts with one click. The tray has a "Check for updates…" item too. Updating from v0.2.0 itself still needs a manual download, since that build has no updater.

Fixed

• Nudges no longer fire right after you log in, come back to the computer, or finally act on a nudge you'd ignored: the next one waits the full interval from that moment, and a nudge still on screen holds back the next.
• Event times are now stored as true UTC and shown in your local time zone, so logged times no longer read hours ahead outside the app. Existing history is converted once on upgrade, and day boundaries, at-time reminders and nudge intervals stay correct across daylight-saving changes. Quit Budgebell before upgrading, so the old version can't log in the old format after the conversion.
