fix: use stdbuf -o0 cat for unbuffered pipe input, remove debug

Browse Source 
- Changed cat subprocess to stdbuf -o0 cat (unbuffered output)
  so characters arrive immediately through the pipe
- Added cat PID to startup messages for diagnostics
- Removed pipe debug logging (trace.log, pipe.log)
- Cat pipe input confirmed working: read-char returns #\a, #\b, #\Newline
- Remaining issue: frame-message format mismatch with daemon
  (pre-existing, not related to input changes)
