This adds two new propeties to make it easy to get the frontmost (main)
window and the focused terminal within a tab. We already had a property
to get the selected tab of a tab group.
Change split, focus, close, activate window, select tab, close tab, and
close window commands to accept their target object as a direct parameter
instead of a named parameter. This produces natural AppleScript syntax:
activate window (window 1)
close tab (tab 1 of window 1)
split (terminal 1) direction right
instead of the awkward redundant form:
activate window window (window 1)
close tab tab (tab 1 of window 1)
split terminal (terminal 1) direction right
The implementation moves command logic from NSScriptCommand subclasses
into responds-to handler methods on ScriptTerminal, ScriptWindow, and
ScriptTab, which is the standard Cocoa Scripting pattern for commands
whose direct parameter is an application class.
Add scripting dictionary commands for activating windows, selecting tabs,
closing tabs, and closing windows.
Implement the corresponding Cocoa AppleScript command handlers and expose
minimal ScriptWindow/ScriptTab helpers needed to resolve live targets.
Verified by building Ghostty and running osascript commands against the
absolute Debug app path to exercise all four new commands.
Add a `name` property (code `pnam`, cocoa key `title`) to the window, tab,
and terminal classes in the scripting definition. This follows the standard
Cocoa scripting convention where `name`/`pnam` maps to the `title` KVC key,
matching what Apple does in CocoaStandard.sdef for NSWindow.
Also fixes the pre-existing terminal `title` property which used a custom
four-char code (`Gttl`) that AppleScript could not resolve directly — only
via `properties of terminal`. All three classes now use the standard `pnam`
code so `name of window 1`, `name of tab 1 of window 1`, and
`name of terminal 1` all work correctly.
Expose terminal surfaces as elements on both ScriptWindow and ScriptTab,
allowing AppleScript to enumerate terminals scoped to a specific window
or tab (e.g. `terminals of window 1`, `terminals of tab 1 of window 1`).
Changes:
- Add `<element type="terminal">` to window and tab classes in Ghostty.sdef
- Add `terminals` computed property and `valueInTerminalsWithUniqueID:`
lookup to ScriptWindow (returns all surfaces across all tabs)
- Add `terminals` computed property and `valueInTerminalsWithUniqueID:`
lookup to ScriptTab (returns surfaces within that tab)
