Add a safe neutralization pass for Stage 4 runtime proxy actors and document the change. Introduces NeutralizeProxyActor and supporting helpers (ProxyNeutralizationReason, GetProxyNeutralizationReasonLabel, FormatPosition, IsProxyMovementPackageType, IsProxyFleeOrAlarmPackageType) plus kProxyNeutralizationInterval and a compile-time gate kEnableProxyAIMovementIntentSuppression (default=false). Adds SuppressProxyAIMovementIntent (default-disabled due to a crash observed during testing) which attempts safe package/process interruption using only confirmed CommonLibF4 APIs (EndInterruptPackage, InitiateDoNothingPackage, SetAvoidanceDisabled, command/process handle clears) and extensive throttled logs and TODOs for further unsafe changes. Neutralization is invoked after spawn promotion, on slot reassignment, during active maintenance, and while holding. Updates plugin logic to call neutralization at these points. Updates docs/architecture.md and docs/dev-log.md with the design, testing notes, and rationale (including the safety gate and next steps). Builds succeed; manual in-game validations are still pending.
