fix: use read-event with ctrl flag, add resize handling

- Switched back to read-event be :timeout 0.01 for proper key-event
  dispatch with the ctrl/alt/shift flags
- Fixed Ctrl+P/B/Q/L dispatch: check key-event-ctrl flag to
  construct :CTRL-<key> keyword symbol (read-event returns :P + ctrl=t,
  not :CTRL-P)
- Added :size-queried state flag and post-handshake backend-size re-query
- Removed hardcoded Connected v0.5.0 message from connect-daemon
- Removed Connected v0.7.2 system message (version shown in status bar)
- view-status now uses draw-rect for background (instead of dotimes loop)
- Added startup message showing backend type and detected dimensions
