Resolves#7591
This moves our CI to build macOS on Sequoia (macOS 15) with Xcode 26,
including the new macOS 26 beta SDK.
Importantly, this will make our builds on macOS 26 use the new styling.
I've added a new job that ensures we can continue to build with Xcode 16 and
the macOS 15 SDK, as well, although I think that might come to an end
when we switch over to an IconComposer-based icon. I'll verify then. For
now, we continue to support both.
I've also removed our `hasLiquidGlass` check, since this will now always
be true for macOS 26 builds.
This integrates with macOS accessibility APIs to expose Ghostty terminal
structure and content.
This is a very, very bare implementation and the terminal contents
currently reported are the _full screen and scrollback_ which is way too
much for realistic human accessibility use. The target use case for this
PR is to enable automated tooling (namely, AI screen readers). However,
this is all groundwork we'll need to iterate and improve the
accessibility work anyways.
To make this work, I also replatformed some of our hacky C APIs onto a
more robust `ghostty_surface_read_text` API that can now read arbitrary
ranges of the screen into C strings for consumers to use. This will be
useful in more places going forward (hint hint).
## Before
Accessibility tooling can't read anything, Ghostty has no attributes, no
contents, just shows up as a square.
## After
A lot of metadata, including the screen contents as text.
Also, split hierarchies are navigable:

This fixes a regression from our Tahoe window styling changes on
earlier, stable versions of macOS. We need to set
"titlebarAppearsTransparent" to true in order to hide the bottom
border.
This is recommended for macOS Tahoe and all standard menu items now have
associated images. This makes our app look more polished and native for
macOS Tahoe.
On earlier versions of macOS (macOS 15 and earlier), we _do not_ set the
menu item image. Cocoa has supported menu item images for a long time
but it isn't idiomatic to show them in earlier versions, so we only do
this for later macOS versions.
For icon choice, I tried to copy other native macOS apps as much as
possible, mostly from Xcode. It looks like a lot of apps aren't updated
yet. I'm absolutely open to suggestions for better icons but I think
these are a good starting point.
One menu change is I moved "reset font size" above "increase font size"
which better matches other apps (e.g. Terminal.app).

Windows with `macos-titlebar-style = hidden` create new windows when the
new tab binding is pressed. This behavior has existed for a long time.
However, these windows did not cascade, meaning they'd appear overlapped
directly on top of the previous window, which is kind of nasty.
This commit changes it so that new windows created via new tab from a
hidden titlebar window will cascade.
Fixes#7546
SwiftUI uses type and structure to identify views, which can lead
to issues with tree like structures where the shape and type is the same
but the content changes. This was causing #7546.
To fix this, we need to add explicit identity to the split tree view
so that SwiftUI can differentiate when it needs to redraw the view.
We don't want to blindly add Hashable to SplitTree because we don't want
to take into account all the fields. Instead, we add an explicit
"structural identity" to the SplitTreeView that can be used by SwiftUI.
