// ClearAECrashState removes the markers After Effects uses to decide it crashed,
// so the blocking "Crash Repair Options" (Safe Mode) dialog never appears on a
// headless launch. Two parts:
//
//  1. SCRPriorState.json in each AE prefs version dir (session crash-recovery state).
//  2. HKCU\Software\Adobe\After Effects\AppStates — AE writes a per-session GUID
//     subkey on startup and removes it on a clean exit; a leftover one (after a
//     kill/crash) triggers Safe Mode. reg.exe is a Windows built-in (no external
//     dep / cgo), so we shell out to it.
//
// Targeted (vs. wiping all prefs) so the node keeps its AE preferences. Safe no-op
// on non-Windows (APPDATA unset).
