Changes since 3.3.2:
- Two display settings, Date format and Week starts on. "Auto" reads navigator.language and uses only the built-in Intl APIs (DateTimeFormat.formatToParts and Intl.Locale week info, with a bundled region table as fallback). No new data is sent anywhere or collected.
- A small CSS fix in the Core Time panel.

Small refinements to the About section in Settings.

Minimal bug fixed.

Daylight saving alerts

Skies now warns you two weeks before a clock change moves the gap
between you and a city.

The case nobody notices: you don't change your clocks at all, your
colleague does, and the recurring meeting you've had for months quietly
shifts by an hour. Skies tells you in plain terms — "In 9 days, Boston
shifts to EST. Your gap: 13 hours → 14 hours."

• A banner appears two weeks ahead, and you can dismiss it
• City cards flag an upcoming change
• Lead time is adjustable in Settings, or you can turn it off entirely
• Southern hemisphere changes go the other way, and that's handled
• Free for everyone

No new permissions. Skies still requests none at all, and still works
fully offline.
