Replace queue-based key dispatch with process-key-event (inline in reader,
zero latency between keypress and render).
Add with-frame to cl-tty.backend (error-safe begin-sync/end-sync wrapper).
Use with-frame in redraw instead of manual begin-sync/end-sync.
Add initial render before main loop (UI appears before first read-event).
Remove position-cursor (replaced by inline block cursor in view-input).
Remove input-string/input-insert-char/input-delete-char wrappers.
Remove :input-buffer/:cursor-pos from state (managed by text-input widget).
passepartout script: set *debugger-hook* nil and failure-behaviour :warn
before quickload to survive compile warnings; remove cache-clear line.
