Fixes#3119
Supersedes #3099
ConEmu and iTerm2 both use OSC 9 to implement different things. iTerm2
uses it to implement desktop notifications, while ConEmu uses it to
implement various OS commands.
Ghostty has supported iTerm2 OSC 9 for a while, but it didn't (and
doesn't) support ConEmu OSC 9. This means that if a program tries to
send a ConEmu OSC 9 to Ghostty, it will turn into a desktop
notification.
This commit adds parsing for ConEmu OSC 9 progress reports. This means
that these specific syntaxes can never be desktop notifications, but
they're quite strange to be desktop notifications anyway so this should
be an okay tradeoff.
This doesn't actually _do anything with the progress reports_, it just
parses them so that they don't turn into desktop notifications.

Fixes#3114
I forgot that the format gets parsed as a Zig string so putting it in
already parsed made `+list-keybinds` incorrect. It worked either way but
this fixes the `+list-keybinds` CLI action.

A follow-up on #3103, the `Style.eql` function can also benefit from
`PackedStyle`.
Using the same DFZ benchmark,
New: 795 FPS
Old (fddedd7c): 765 FPS
FPS is a bit different due to differing background system loads, but the
increase in FPS is consistent across benchmarks.
# Description
This commit introduces the ability to launch the quick terminal in the
middle position.
## Note to reviewer
- The quick terminal is currently centered. Should we consider adding a
top offset to better align with the screenshot in [the issue](#2494 )?
Should it be configurable?
- On large monitors, half the visible frame might be excessively large.
To mitigate, I am planning to implement #2384 but we should probably
agree on a good default maximum width/height in middle position.
- I also figured out, reloading the configuration does not update the
quick terminal configuration. That is also an issue I will try to fix.
Resolves#2494
I agree to relicense my commit to MIT.

This breaks fixterms encodings for these specific keys so that shells
and other programs that rely on the legacy encoding for these keys will
work by default.
This only does this for macOS because for whatever reason during the
large beta period, only macOS users found this as lacking.
If users want to restore fixterms behaviors, they can rebind these keys
as `unbind`.

...unless ~/.config/ghostty/config already exists, then that is opened.
(Or whatever $XDG_CONFIG_HOME points to.)
If both files exists, ghostty reads first the one in
~/.config/ghostty/config and then the one in Application Support, and
merges the settings. In that case, the menu item opens the file at
~/.config.

The idea is to serialize `Style` into a packed format as quickly as
possible.
Following an SOA pattern here yields the best result.

Memory usage isn't affected as the layout changes cancel each other out.
Back out "perf(styles): greatly improve style.hash performance" This
backs out commit 3bfe4cd25ca7a5ae4d4084818b86ada9236b3bb5, but keeps the
hash algorithm as XxHash3 which showed improvements in performance.
Back out "perf(styles): greatly improve style.hash performance"
This backs out commit 3bfe4cd25ca7a5ae4d4084818b86ada9236b3bb5, but
keeps the hash algorithm as XxHash3 which showed improvements in
performance.
To preface, I tested the impact of these changes by running
DOOM-fire-zig in a 120x30 window on a ReleaseFast build. I feel that
DOOM-fire-zig is a fairly realistic target when it comes to "high style
use" terminal applications.
1. By adjusting the conditions under which we swap items while inserting
in to our hash table in `RefCountedSet` we can prioritize styles with
many refs, so they're more likely to stay near their target bucket. This
change brought DFZ FPS from ~700 to ~840, or a roughly 20% improvement.
2. By changing how we hash `Style` structs, we can avoid a lot of
unnecessary overhead and benefit from smaller i-cache size as well as
xxHash's better statistical qualities when compared to Wyhash. This
change brought DFZ FPS from ~840 to ~1020, or another roughly 20%
improvement.
These two changes combined represent as roughly 45% improvement over
`main`, which is... pretty good I'd say.
In addition, I've run `vtebench` and there is no significant difference
in the results between this PR and main.
By switching to one-shot hashing of the raw bytes of the struct with
XxHash3 instead of using `autoHash` with Wyhash, a performance gain of
around 20% can be observed in DOOM-fire-zig.
Fixes#2841
We were incorrectly applying the start/end x offset for the first/last
row of every single page. If a selection spanned multiple pages this
would trim data incorrectly.
Unit test updated to cover this case.

Fixes#2332
Two bugs fixed to fix this behavior:
1. Our destination height didn't account for the top-left being
offscreen.
2. We were using the wrong height for the source rectangle. When a rows
param (r=) is specified, the image height and destination height are at
different scales. We were using the viewport scale for the offset but it
should be the image scale.

Fixes#2497
While investigating the issue I added an integrity check that found a
problem hiding in the insert logic that was unrelated- in fixing that I
greatly simplified the insert logic.
It turns out that #2497 is ultimately just a case of bad luck,
pathological inputs that result in very non-uniform hashes so the
clustering overwhelms things. The solution was just to add a check and
claim we're out of memory.
I tried adding an entropy folding function to fix the hash a little but
it had a measurable negative impact on performance and isn't necessary
so I've not included it here. Currently there's an open PR to Zig to
[add RapidHash](https://github.com/ziglang/zig/pull/22085), which is the
successor to Wyhash and apparently has much better statistical
characteristics on top of being faster. I imagine it will land in time
for 0.14 so whenever we update to 0.14 we should probably switch our
standard hash function to RapidHash, which I imagine should yield
improvements across the board.
Using the AutoHasher may also be not the best idea, I may explore ways
to improve how we generate our style hashes in the future.
According to the GNOME human interface guidelines, buttons for the main
user actions, such as new, add, open, and back should be placed at the
start of the header bar.

Moving the new tab button to the start of the header bar brings Ghostty
in line with other GNOME applications such as gedit and gnome-terminal.
Fixes#2958
The y was alround bounded but we allowed any x value and assumed the
caller would handle it. This is not the case so we now check the x and
return null if it's out of bounds (same as y, which was already doing
this).

Poor hash uniformity and/or a crafted or unlucky input could cause the
bounds of the PSL stats array to be exceeded, which caused memory
corruption (not good!) -- we avoid such cases now by returning an
OutOfMemory error if we're about to insert and there's an item with a
PSL in the last slot.

Our z-index handling was pretty much completely broken, hence I can't
think of a better initial commit message. We were splitting the
placements at the wrong points and just generally putting images in the
wrong z-index. I'm shocked this didn't come up earlier.

Previous logic had multiple issues that were hiding in edge cases of
edge cases with the ressurected item handling among other things; the
added assertIntegrity method finds these issues, the primary one being
an edge case where an ID is present in two different buckets.
Added more comments to explain logic in more detail and fixed a couple
little things like always using `+%` when incrementing the probe pos,
and replacing a silent return on an integrity issue that should be
impossible (`table[item.meta.bucket] != id`) with an assert.

There was an accidental use of `undefined` which I believe is the source
of crashes people are experiencing when drawing Powerline chevrons
(#3083). I've resolved this by using the slice from the path's internal
`ArrayList` instead of the backing array (`z2d` should probably
introduce a `getNodes()` method or similar to `StaticPath`), and also
annotated all `StaticPath` uses counting the maximum number of nodes
that may be required.
(**Edit**: confirmed, fixes#3083)
Annotate the node count of all uses of z2d `StaticPath` to verify
correctness, adjusted the size of a couple which were oversized, and
changed all painter calls that take node slices from `StaticPath`s to
use the slice from the wrapped `ArrayList` so that we don't include any
potentially `undefined` nodes at the end of the list, which I think was
causing a crash before.
Fixes#2092
This isn't perfect because it only prevents _new_ splits from being too
small. You can still resize the window to make them smaller. This just
helps prevent the very-easy-to-trigger crash of #2092.
We don't need to do this to macOS because it doesn't crash in the same
way with zero-sized splits.
Long term we should really chase down what breaks in GTK at a root level
when we have zero-sized splits. But this is a quick fix for now to
prevent the easy crash I feel like people might stress test and run into
with the 1.0 release.

The justification there makes sense to me and I think it would be a good

bindings in the Window > Resize Split menu and thus looks more elegant
and is easier to memorize.

is usually associated with extending a selection. Cmd-up/down are
available (they currently act as simple up/down). I bind them
additionally to the defaults.
