jgrusewski 2f4bd8e58b cleanup(dqn): remove val-collapse diagnostic printf — fix verified

Diagnostic kernel printf in backtest_env_step_batch identified the gate
(Kelly cap warm-branch deadlock) and verified the fix
(0c9d1ee39: max(kelly_f, warmup_floor)) on train-4r6p8:

  Before fix (train-4fpzx, fresh model epoch 0):
    val_picked_dir_dist [short=0.19 hold=0.20 long=0.39 flat=0.21]
    val_dir_dist        [short=0.0001 hold=0.20 long=0.0000 flat=0.80]
    trade_count = 23 over 214K bars  (active_frac = 0.0001)

  After fix (train-4r6p8, fresh model epoch 0):
    val_picked_dir_dist [short=0.24 hold=0.17 long=0.42 flat=0.17]
    val_dir_dist        [short=0.24 hold=0.17 long=0.42 flat=0.17]   1:1
    trade_count = 139,695 over 214K bars  (active_frac = 0.6590)

  Picked and realised distributions now bit-identical — every Boltzmann
  pick translates faithfully to actual_dir.
