Fixes#8415
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.

hand-modified the end.

I've been using agents a lot more with Ghostty and so are contributors.
Ghostty welcomes AI contributions (but they must be disclosed as AI
assisted), and this AGENTS.md will help everyone using agents work
better with the codebase.
This AGENTS.md has thus far been working for me very successfully,
despite being simple. I suspect we'll add to it as time goes on but I
also want to avoid making it too large and polluting the context.
**Changes should not be made to `AGENTS.md` unless it demonstrably
improves agent behavior.** To demonstrate agent behavior, I'd prefer
sharing an amp thread before and after the change with the same prompt
and model to show an improvement.
This has no meaningful functionality yet, it was one of the paths I was
looking at for #8505 but didn't pursue further. But I still think that
this makes more sense in general for the macOS app and will likely be
more useful later.

Fixes#8356
Zoom state should encode as a path so that it can be mapped to a
reference to the node in `root`. Previously, we were encoding a full
node which was instantiating an extra terminal on restore.
AI disclaimer: Claude code did the Codable implementation.

Make the default keybind for copy_to_clipboard performable. This allows
TUIs to receive events when keybinds aren't used, for example cmd+c on
macos for copy, or ctrl+shift+c elsewhere.

Fixes#8495
We were incorrectly calling graceful quit under must quit scenarios.
This would do things like confirm quit by inspecting for running
processes. However, must quit scenarios (namely when all windows are
destroyed) should quit immediately without any checks because the
dispose process takes more event loop ticks to fully finish.

Addresses issue: Add selection-clear-on-copy configuration #8407
Added configuration option `selection-clear-on-copy` that matches with
the `selection-clear-on-typing` option.
And `copy-on-select` is ignored when `selection-clear-on-copy` is true
regardless of whether `copy-on-select` is set to true or clipboard.
Also `.copy_to_clipboard` binding action was refactored to use
`copySelectionToClipboards` for consistent behavior.
> Consulted with Copilot (Claude Sonnet 4) to understand the control
flow of copy operations and help write the docs. Solution was authored
and implemented by me.
This is a small, but I think worthwhile micro optimization in style.zig,
I uncovered while investigating wider ranging optimizations in the
rendering section.
For me it results in ~4-5% increase in fps for DOOM-fire-zig benchmark,
which maximally stresses this code path.
Comparing the fields directly is actually faster than PackedStyle.
I wrote the code in style.zig, claude 4 wrote the benchmark, all PR
responses will be generated by jcm-slow-1

Fixes#2473
This commit changes `ghostty_surface_ime_point` to return a full rect
with the width/height calculated for the preedit.
The `firstRect` function, which calls `ghostty_surface_ime_point` was
previously setting the width/height to zero. macOS didn't like this. We
then changed it to just hardcode it to width/height of one cell. This
worked but made it so the IME cursor didn't follow the preedit.
The result is shown in the video below. Notice the dictation icon
follows the text properly:

Fixes#8481
Explained in code comments, basically the NF patcher can produce fonts
that have CJK characters with 1-cell advances, which screws up fallback
font scaling; fixed by not counting the ic width metric if the width of
the glyph is greater than the advance width.
> [!NOTE]
> As follow-on work to this it may be worth setting limits for scaling,
so you can't have one font scaled like twice as large as the primary
font, since that's almost always going to indicate something is very
wrong.

When processing kitty images in a loop in a few places we were returning
under certain conditions where we should instead have just continued the
loop. This caused serious problems for kitty images, especially for apps
that used multiple images on screen at once.
... I have no clue how I originally wrote this code and didn't see such
a trivial mistake, I think I was sleep deprived or something.

This pull request adds the `--faint-opacity` option, as discussed in
#7637.
The default value of the option is also changed from `0.68` to `0.5` for
greater consistency with other popular terminal emulators.
Fix for discussion #8113
The cursor Y position value exposed to the shader uniforms was
incorrectly calculated. As per the doc in cell_text.v.glsl: In order to
get the top left of the glyph, we compute an offset based on the
bearings. The Y bearing is the distance from the bottom of the cell to
the top of the glyph, so we subtract it from the cell height to get the
y offset.
This calculation was mistakenly left out of the original code.
This will ensure that the custom shaders using
iCurrentCursor/iPreviousCursor get the correct Y coordinate representing
the top-left corner of the cursor rectangle, matching the documented
uniform behavior
This math was incorrect from the start, the previous fix helped OpenGL
but broke positioning under Metal; this commit fixes the math to be
correct under both backends and adds comments explaining exactly what's
going on.
