landing: overhaul client listings with accurate March 2026 data
- Replace flat client buttons with descriptive cards showing platforms, features, and caveats
- Cinny featured card: "Voice & Video Rooms" (accurate — not DMs, space rooms only)
- Element X: correct platforms (iOS/Android only), add Rust SDK + Screenshare tags
- FluffyChat: add "Calls Experimental" tag with homeserver caveat
- Commet: fix to Android/Windows/Linux only (remove incorrect iOS listing), add multi-account/GIF/calendar notes
- Element desktop: add Screenshare tag, note resource usage
- Nheko: add as native lightweight desktop alternative
- Remove SchildiChat (unverified/outdated)
- Add encryption security note (Vodozemac Rust SDK vs matrix-js-sdk)
- Add new CSS: .client-card, .tag.rust, .tag.experimental, .tag.platform, .security-note
