v1.9.4: decode_step/hunt byte-replay tests + hunt EOF guard

Browse Source 
- tests: TestDecodeStep drives decode_step() with a scripted byte queue
  (read/peek/consume stubbed over _replay + the queue; the re-align/PPS/
  ATR/annotation sinks stubbed): 'CX'/'EX' exchanges frame and emit clean,
  0x5F frames as a command (it was always eaten by the idle-noise gate
  before v1.9.3), the 0x61 text-byte boundary is a one-byte suspicious-CLA
  discard, the invalid-INS re-frame recovers a shifted SELECT, 0xFE still
  takes the idle-noise path.
- tests: TestAtrHuntDetect drives handle_atr(): 0xC4 0xA4 / 0xC4 0x89
  hand the header to DATA via _replay, CLA 0x00 stays excluded, an invalid
  INS does not hand off.
- pd.py: the hunt command-detect guards peek_byte() returning None (a
  capture ending right after a plausible CLA byte raised TypeError, seen
  only by decode()'s crash protection);
  test_eof_after_plausible_cla_is_clean pins the clean return.
- AGENTS v1.9.4 section; baseline regenerated (version + test listing;
  compare_baseline: IDENTICAL); 95/95 unit tests.
