Desktop widgets

What's new

• Desktop widgets. Three sizes: small (single port), medium (all ports at a glance), and large (all ports with full detail). The widgets update live whenever cable state changes. Add them from the macOS widget gallery under "WhatCable".

• Device count badge. Ports with USB devices connected show a small count indicator on all three widget sizes.

• Confirmed TB5 labels. Thunderbolt 5 links now show "Thunderbolt 5" instead of the hedged "Unknown generation (inferred TB5)" wording. Thanks to contributors who shared TB5 endpoint data on #52.

• Cable database page. Known cables reported via the in-app flow are now listed at whatcable.uk/cables, searchable by brand or vendor ID.

Other

• Docs and CLI documentation pages added to whatcable.uk.
• Footer and about panel now show "WhatCable" instead of a personal name.
• Cable report sync script for maintaining the known-cables database.
