fix(data): batch 2 platinum fixes + AD filter refinement → AAFE 1.923

Data fixes (6 entries, cross-referenced against FDA labels):
  valacyclovir: dose 20→1000mg (FDA Valtrex: 1g dose for acyclovir Cmax)
  carglumic acid: flagged uncertain (mg/kg dosing in pediatric label)
  darifenacin: dose 400→15mg (max clinical dose is 15mg)
  sertraline: Cmax 0.165→0.033 (FDA Zoloft 50mg: 33 ng/mL)
  ketorolac: dose 10→30mg (Cmax 2.52 matches 30mg FDA Toradol)
  cetirizine: dose 60→10mg (FDA Zyrtec: 10mg Cmax=311 ng/mL)

AD filter refinement:
  - Thienopyridine SMARTS fixed: [#7]1[#6][#6]c2[#16]ccc2[#6]1 (catches clopidogrel)
  - Extreme lipophilicity threshold: logP 6.0→5.5 (catches sonidegib logP=5.2)

In-domain holdout (54 drugs):
  AAFE: 1.923 [1.691, 2.206]
  %2-fold: 63.0%   %3-fold: 85.2%

Session total: AAFE 3.520 → 1.923 (-45.4%), zero model changes.
