Adds `wsh attach` — a command that streams the live output of any Wave Terminal block to a local terminal window without affecting the remote session. Useful for monitoring long-running processes, CI jobs, or AI coding agents from a separate window or SSH session. Key capabilities: - Interactive block selector (workspace → tab → block) - Live PTY streaming via snapshot + WPS event subscription - Viewport model: server PTY size is fixed; local terminal is a moveable window into the remote screen (Ctrl+Arrow to pan) - Diff-based renderer that emits only changed cells per frame, with full SGR, wide-character, alt-screen, and cursor-style sync - Debounced render loop (16 ms) coalesces rapid PTY bursts so that full-screen TUI repaints are always consumed before rendering - Resync command (Ctrl-A s) rebuilds xterm-go state from a fresh snapshot when local state drifts from the remote Bug fix included: EventRecv messages are now dispatched synchronously in the WshRpc message loop (same pattern as StreamData/StreamDataAck) so that back-to-back PTY events are always processed in arrival order. Without this fix, concurrent goroutines race to write PTY chunks into the terminal emulator, producing mixed-frame garbling.
