Rename: cl-tty avoids naming collision with Quicklisp's cl-tui (naryl/cl-tui, a cl-charms-based ncurses library). Our project is pure escape-sequence CL. v0.9.0 adds: - Dialog base class: modal overlay with backdrop, centered panel, size variants (:small/:medium/:large), stack-based management - Dialog subclasses: alert, confirm, select-dialog, prompt-dialog - Toast notifications: transient, top-right corner, auto-dismiss, colored variants (info/success/warning/error) - 78 tests total, 100% passing ASDF: read-time package references (+fiveam:+) replaced with find-symbol so .asd loads without FiveAM pre-loaded
