Mitchell Hashimoto fd5ad1f574 macos: add AppleScript commands for text input, key, and mouse events
Add five new AppleScript commands to Ghostty.sdef mirroring the existing
App Intents for terminal input:

- `input text`: send text to a terminal as if pasted
- `send key`: simulate a keyboard event with optional action and modifiers
- `send mouse button`: send a mouse button press/release event
- `send mouse position`: send a mouse cursor position event
- `send mouse scroll`: send a scroll event with precision and momentum

A shared `input action` enumeration (press/release) is used by both key
and mouse button commands. Modifier keys are passed as a comma-separated
string parameter (shift, control, option, command).
