Disable contextmenu on non-secondary `pen` events or `touch`

Editor assessment

The subject states the input rule precisely: the context menu is suppressed for non-secondary pen events and touches, with backticked event names aiding clarity. The fix type suits the gesture defect, and the absent scope is tolerable. No body is present, which is acceptable because the subject enumerates the suppressed inputs and the suppressed behavior completely. The PR reference is well-formed. Imperative mood, no trailing period, slightly long but information-dense subject. A precise, self-sufficient interaction-fix message.
