cursor: hide while typing and after touch input

Typing hides on a real keystroke only — a bare modifier press is excluded
so Super+drag keeps its cursor. Touch hides until the pointer next moves,
which the reveal rule enforces via HideReason::Touch.

Drafted with Claude (Anthropic); reviewed and tested by the committer.
