dispatchKeyEvent only handled keyDown, returning early for keyUp, rawKeyDown, and char types. This meant JS keyup and keypress listeners never fired via CDP. Now keyUp dispatches as "keyup" and char dispatches as "keypress". rawKeyDown remains a no-op (Chrome-internal, not used for JS dispatch). Fixes #2080 Ref #2043
