Add search, media viewer, WhatsApp-style UX (v1.12.0)

[Meemkhaan]

Summary

Fork with UX and feature improvements inspired by WhatsApp: search, jump-to-date, media viewer, and better defaults.

Added

• Search Messages – Search by author or message text with highlight; Jump to date calendar to view a specific day
• Who are you? – Prominent selector so “your” messages show on the right; choice stored in localStorage
• Media viewer – Click images/videos to open in a full-screen lightbox (Escape to close)
• Improved audio – preload="metadata", styled container, accessible labels
• Toast notifications – In-app toasts instead of alert() for errors
• Export visible messages – Download current filtered list as .txt
• Clear filters – One-click reset to show all messages
• Scroll to top – Floating button for long chats
• Virtual list – react-virtuoso for better performance on long chats
• Accessibility – Skip-to-messages link, aria-labels, focus trap in sidebar
• i18n – Centralized UI strings in src/i18n.ts
• Vercel – vercel.json with outputDirectory: build for deployment

Changed

• Show all messages by default – No more 1–100 limit; full chat until you filter
• Timestamp layout – Date/time on its own line below the bubble (WhatsApp-style)
• Sidebar order – “Who are you?” and “Search Messages” first
