feat: scaffold IRC-style CLI client (chat-cli)

Adds cmd/chat-cli/ with: - tview-based irssi-like TUI (message buffer, status bar, input line) - IRC-style commands: /connect, /nick, /join, /part, /msg, /query, /topic, /names, /list, /window, /quit, /help - Multi-buffer window model with Alt+N switching and unread indicators - Background long-poll goroutine for message delivery - Clean API client wrapper in cmd/chat-cli/api/ - Structured types matching the JSON message protocol
