v0.0.7.13 — Catching up to the rebuilt Amex Travel site (since 0.0.6.3)

Amex relaunched travel.americanexpress.com on Next.js + MUI in April–May 2026. Every surface the extension touches changed: URL shape, flight-card DOM, duration format, Flight Details modal, and loading screen. This release rolls up the adjustments shipped since 0.0.6.3.

• Site coverage: rebuilt travel.americanexpress.com, its www. subdomain, and root-domain americanexpress.com/<locale>/travel/ routes — alongside the legacy amextravel.com.
• Layover pills: every layover gets a green/yellow/red severity pill (red <60min, green 60min–4h, yellow >4h) — on cards, Amex's route-line indicator, the Flight Details modal summary line, and every entry in the popup ranked list. Both "Xh Ym" and sub-hour "55min" formats are matched.
• Popup polish: single-stop itineraries no longer show the layover total twice.
• Dark mode on the new site: skeleton shimmer, progress bars, loaders, and the "AMERICAN EXPRESS TRAVEL" brand wordmark all render correctly during search loading.
• Messaging: manifest description and popup tagline refreshed to lead with severity color-coding (Amex re-exposed the layover times themselves, so the extension's unique value is now the highlighting).
