test(calibration): 8 labels + 3 scenarii noi (inclusiv regresie 2026-04-21)

calibration_labels.json: 16 → 24 entry-uri. Toate cele 8 frame-uri dumpate
automat de live loop azi (gray×5, dark_green×1, yellow×1, dark_red×1) trec
prin validate-calibration cu detector-ul curent (24/24 PASS).

scenarios.json: 8 → 11 scenarii:

1. buy_catchup_opposite_rearm_to_sell — REGRESSION pentru bug-ul de azi.
   Trace real din log: 17:00 catchup dark_green → PRIMED_BUY (synth arm+prime),
   apoi 17:45 yellow → ARMED_SELL via opposite_rearm. Verifică că dispatch-ul
   nou emite kind=opposite_rearm și că scheduler-ul se oprește.

2. buy_armed_gray_persist — gray între arm și prime ține ARMED_BUY
   (reason=persist). Acoperă o ramură FSM neacoperită.

3. buy_primed_gray_cooldown — gray după prime ucide ciclul (reason=cooled,
   IDLE, scheduler stop). Confirmă semantica M2D că chart-ul tăcut post-prime
   înseamnă setup expirat.

Total: 11/11 scenarii PASS, 238/238 teste (235 + 3 noi scenarii regresie).
