New clock/ package replaces the old design() polling loop with a flicker-free ANSI cursor-positioned renderer. Features include: countdown timer, epoch/halving progress bar, fee rate indicator, hashrate sparkline, matrix mining animation, odometer digit transition, heartbeat pulse, zen mode, UTC time display, fireworks on milestone blocks, generative hash art, and configurable sound modes. All features are toggleable via Settings → D (Clock Display Settings). Also fixes hardcoded config paths in menuSelection(), menuSelectionLN(), and TUI startup to use the cfg singleton instead.
