Two major changes:
1. Hiding uses `NSApp.hide` which hides all windows, preserves tabs, and
yields focus to the next app.
2. Unhiding manually tracks and brings forward only the windows we hid.
Proper focus should be retained.
Fixes#4703
This changes `unbind` so it always removes all keybinds with the given
trigger pattern regardless of if it is translated or physical.
The previous behavior was technically correct, but this implements the pattern
of least surprise. I can't think of a scenario where you really want to
be exact about what key you're unbinding. And if that scenario does
exist, you can always fix it by rebinding after unbind.
In #4388, documentation was added for goto_split but in #3427 this
documentation was made outdated but not updated. This makes the
documentation up to date and brings the ordering in line with new_split
Fixes#4518
If our UTF8 encoding is not recognized, we fall back to the ASCII
mapping of the logical key for the control sequence. This allows
cyrillic control characters to work.
I also verified that non-cyrllic (US) and alternate layouts (Dvorak)
work as expected still.

Current sort used by `+list-keybinds` doesn't include the value of the
key:
```
ctrl + shift + v paste_from_clipboard
ctrl + shift + a select_all
...
ctrl + shift + q quit
ctrl + shift + n new_window
...
alt + five goto_tab:5
alt + eight goto_tab:8
...
alt + six goto_tab:6
alt + seven goto_tab:7
```
adding the key value improves the sort order
```
ctrl + shift + a select_all
ctrl + shift + c copy_to_clipboard
...
ctrl + shift + n new_window
ctrl + shift + o new_split:right
ctrl + shift + q quit
...
alt + one goto_tab:1
alt + two goto_tab:2
alt + three goto_tab:3
...
alt + eight goto_tab:8
alt + nine last_tab
alt + f4 close_window
closes#4328closes#3970
makes this possible now
```
keybind = performable:ctrl+c=copy_to_clipboard # copy if theres a selection else send sigint
keybind = ctrl+v=paste_from_clipboard
```
Renames the top/bottom directions of `goto_split` to up/down. I have
tested this on linux (nixos) but given that `goto_split` is broken on
linux anyway (#2866) there's not a whole lot to test.
I have no way to build on macOS so I can't verify that I've changed
everything correctly for that.
Closes#3237
The [fixterms](http://www.leonerd.org.uk/hacks/fixterms/) "Really
Special Keypresses" section suggests using CSI 1 ; Ps R for F3, but this
is also a valid cursor position report. The intention was to make
back-compatible changes, so this is fairly considered a specification
bug.
This changes F3 in legacy mode to send CSI 13 ; Ps ~ instead, this is a
variant listed in fixterms, is what kitty protocol uses, and lacks the
problematic overlap with cursor positions.
The KeyEncoder.zig unit test has been changed accordingly, and all tests
pass on my machine.

The comment in `function_keys.zig` was missing the `>` character for the
sequence. I've confirmed that this was just the comment, Ghostty treats
the original as an SGR sequence, which it is. Conversely, it does treat
`\x1b[>4:2m` as activating modifyOtherKeys.
**Context**
Currently, if there are multiple keybindings with a shared prefix,
they are grouped into a nested series of Binding.Sets.
For example, as reported in #2734, the following bindings:
keybind = ctrl+z>1=goto_tab:1
keybind = ctrl+z>2=goto_tab:2
keybind = ctrl+z>3=goto_tab:3
Result in roughly the following structure (in pseudo-code):
Keybinds{
Trigger("ctrl+z"): Value.leader{
Trigger("1"): Value.leaf{action: "goto_tab:1"},
Trigger("2"): Value.leaf{action: "goto_tab:2"},
Trigger("3"): Value.leaf{action: "goto_tab:3"},
}
}
When this is formatted into a string (and therefore in +list-keybinds),
it is turned into the following as Value.format just concatenates
all the sibling bindings ('1', '2', '3') into consecutive bindings,
and this is then fed into a single configuration entry:
keybind = ctrl+z>1=goto_tab:1>3=goto_tab:3>2=goto_tab:2
**Fix**
To fix this, Value needs to produce a separate configuration entry
for each sibling binding in the Value.leader case.
So we can't produce the entry (formatter.formatEntry) in Keybinds
and need to pass information down the Value tree to the leaf nodes,
each of which will produce a separate entry with that function.
This is accomplished with the help of a new Value.formatEntries method
that recursively builds up the prefix for the keybinding,
finally flushing it to the formatter when it reaches a leaf node.
This is done without extra allocations by using a FixedBufferStream
with the same buffer as before, sharing it between calls to nested
siblings of the same prefix.
**Testing**
Besides the included unit tests, I ran the GLFW-based app
and verified that the resulting binary produced the correct output
with `ghostty +show-config`:
```
❯ .zig-cache//o/02a32e7ba516d2692577a46f1a0df682/ghostty +show-config 2>/dev/null | grep goto_tab
keybind = ctrl+z>1=goto_tab:1
keybind = ctrl+z>3=goto_tab:3
keybind = ctrl+z>2=goto_tab:2
```
**Caveats**
We do not track the order in which the bindings were added
so the order is not retained in the formatConfig output.

A common issue for US-centric users of a terminal is that the "option"
key on macOS is not treated as the "alt" key in the terminal.
## Background
macOS does not have an "alt" key, but instead has an "option" key. The "option"
key is used for a variety of purposes, but the troublesome behavior for some
(and expected/desired behavior for others) is that it is used to input special
characters.
For example, on a US standard layout, `option-b` inputs `∫`. This is not
a typically desired character when using a terminal and most users will
instead expect that `option-b` maps to `alt-b` for keybinding purposes
with whatever shell, TUI, editor, etc. they're using.
On non-US layouts, the "option" key is a critical modifier key for
inputting certain characters in the same way "shift" is a critical
modifier key for inputting certain characters on US layouts.
We previously tried to change the default for `macos-option-as-alt`
to `left` (so that the left option key behaves as alt) because I had the
wrong assumption that international users always used the right option
key with terminals or were used to this. But very quickly beta users
with different layouts (such as German, I believe) noted that this is
not the case and broke their idiomatic input behavior. This behavior was
therefore reverted.
## Solution
This confusing behavior happened frequently enough that I decided to
implement the more complex behavior in this commit. The new behavior is
that when a US layout is active, `macos-option-as-alt` defaults to true
if it is unset. When a non-US layout is active, `macos-option-as-alt`
defaults to false if it is unset. This happens live as users change
their keyboard layout.
**An important goal of Ghostty is to have zero-config defaults** that
satisfy the majority of users. Fiddling with configurations is -- for
most -- an annoying task and software that works well enough out of the
box is delightful. Based on surveying beta users, I believe this commit
will result in less configuration for the majority of users.
## Other Terminals
This behavior is unique amongst terminals as far as I know.
Terminal.app, Kitty, iTerm2, Alacritty (I stopped checking there) all
default to the default macOS behavior (option is option and special
characters are inputted).
All of the aforementioned terminals have a setting to change this
behavior, identical to Ghostty (or, Ghostty identical to them perhaps
since they all predate Ghostty).
I couldn't find any history where users requested the behavior of
defaulting this to something else for US based keyboards. That's
interesting since this has come up so frequently during the Ghostty
beta!

The proper way to convert a unicode scalar in Swift is to use the
`String` initializer that takes a `UnicodeScalar` as an argument. We
were converting a number to a string before, which is incorrect.
Fixes a crash found in Discord.
Cloning the keybinding set previously shallow copied the actions, but
actions may contain pointers. These pointer values must be deep copied
to avoid dangling references when the underlying memory is freed.
