v1.9.23: auto-detect PC/SC reader with retry on startup

__main__.py:
- Probe smartcard.System.readers() before init_reader when no reader
  was explicitly specified
- Retry 3 times with 2s delay to handle late pcscd startup and
  USB enumeration delays

start.sh:
- Also match pcscd.bin process name (some distros)
- Wait 1s for pcscd if not running yet
