ValidateTaskPayload

func ValidateTaskPayload(payload json.RawMessage) error

Validate a bounded non-empty JSON task payload.

@param payload: Encoded input or output; it must be valid JSON and no larger than MaxTaskPayloadBytes.
@returns: Nil when valid or a bounded, actionable contract error.

Custom TaskStore implementations should call this at their direct public boundary and still enforce the corresponding database invariants atomically.
