fix: blocking read-char with with-timeout, dialog key routing

Browse Source 
- Replaced read-event (broken on fd 0 in this SBCL) with direct
  blocking read-char wrapped in sb-ext:with-timeout 0.1
- This gives reliable key input + periodic wakeup for daemon messages
- Added dialog key routing back (escape to close, up/down, enter to
  select, character filtering, backspace)
- Fixed # of closing parens to match new structure
- Removed debug logging
