Missing support for press-and-hold keyboard input (keyDown to keyUp) on macOS Computer Use

What platform is your computer?
macOS Sequoia 15.7.7
What issue are you seeing?
Computer Use currently appears unable to hold a key down independently of releasing it. This prevents automating applications that rely on continuous or simultaneous key presses, such as classic computer emulators that poll the keyboard matrix rather than processing discrete key events. Please expose low-level keyDown and keyUp operations (or equivalent) so keys can be held across multiple frames or combined with other keys.
What steps can reproduce the bug?
When Computer Use tries to type into the 'Fuse for macOS' XZ Spectrum emulator. The BASIC operating system often misses the keypresses. Because it periodically scans if the key is pressed a that moment.
Computer Use seems to send a keyDown, keyUp, back-to-back. So the key is rarely pressed at that correct point in time.
What is the expected behavior?
There should be an API to hold the key for a duration longer than the scan interval of some emulator or other old-style 'key matrix scanning' application.
