Maybe fixes#8736
I thought `windowDidLoad` was early on because its before the window is
shown but apparently not. Let's try `awakeFromNib` which is called
just after the window is loaded from the nib. It is hard to get any
earlier than that.
This fixes an issue where new tabs would not have the proper transparent
background set whilst in native fullscreen. This is because in native
fullscreen, the NSTitlebarView always is visible, so our guard was
preventing us from setting it before.
When using hidden titlebar with non-native fullscreen, the window would
lose focus after entering the first command. This occurred because:
1. Shell commands update the window title
2. Title changes trigger reapplyHiddenStyle()
3. reapplyHiddenStyle() re-adds .titled to the style mask
4. Style mask changes during fullscreen confuse AppKit, causing focus loss
Fixed by adding a guard to skip titlebar restyling while fullscreen is
active, using terminalController.fullscreenStyle.isFullscreen for
proper detection of both native and non-native fullscreen modes.

Fixes#7941
I don't fully understand the fix here. Its code we've had for awhile it
was just in the wrong place after I refactored our window management.
The comment clearly states why its there but I don't know why it is
required.
This regression may have existed on Sequoia too, but I only saw it on
Tahoe.
The issue is that we should not be setting up titlebar accessory views
when there is no titlebar. This was triggering an AppKit assertion.
To further simplify things, I always use the basic window styling if
window decorations are off, too.
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 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.
