Stop trying to use POSIX shared memory functions such as `shm_open` on
Android as it's unsupported and the platform libc does not have those
symbols.
This avoids an error such as the below when trying to use
`libghostty-vt` on Android:
> dlopen failed: cannot locate symbol "shm_open" referenced by [..]

Maybe related to #12298?
When Screen resize forwards the active cursor into PageList reflow, a
history-pinned viewport can be remapped into the active area before the
preserved-cursor grow step finishes. The old code kept treating that
viewport as a history pin during the intermediate grow calls, which left
too few rows beneath the pin and tripped the viewport integrity checks.
Fix this by normalizing the viewport back to active as soon as reflow
moves the pinned row into the active area. Add a Screen-level regression
test that exercises the full resize path with bounded scrollback and
wrapped rows, and document the setup so the unwrap and viewport
transition are clear.

This updates simdutf to my fork which has a SIMDUTF_NO_LIBCXX option
that removes all libc++ and libc++ ABI dependencies. The plan is to open
an upstream PR with this, but I want to verify it here first.
From there, the hand-written simd code we have has been updated to also
no longer use any libc++ features. Part of this required removing utfcpp
since it depended on libc++ (`<iterator>`).
libghostty-vt now only depends on libc.
## Benchmark Results
| Corpus | Current `HEAD` median | `main` median | Delta vs `main` |
Notes |
| --- | ---: | ---: | ---: | --- |
| `valid-mixed-1g-seed1.bin` | `9.245s` | `9.111s` | `1.5%` slower |
Near tie; `main` remains slightly faster on fully valid input |
| `malformed-mixed-1g-seed1-rate0.005.bin` | `9.251s` | `12.705s` |
`37.3%` faster | Large improvement on malformed UTF-8 input |
Approximate throughput from the medians:
- Valid corpus: current `HEAD` `110.8 MiB/s`, `main` `112.4 MiB/s`
- Malformed corpus: current `HEAD` `110.7 MiB/s`, `main` `80.6 MiB/s`

This updates our synthetic generator for UTF-8 to expose:
- Flags to change 1/2/3/4-byte UTF-8 character distribution
- Flags to have only printable characters so we can benchmark pure UTF-8
vs our control sequence finder.
- Flags to have invalid characters so we can benchmark our error
handling.
This also adds an AGENTS.md to src/benchmark so agents can do the right
thing more easily.
These are necessary to robustly benchmark our libc++ removal PR.

Closes#11995
Yet another small step to fix menu shortcut-related issues.
1. Create `MenuShortcutKey` from `NSMenuItem` and `KeyboardShortcut`.
2. Add `updateMenuShortcut` to update to Ghostty ones only.
Doesn't contain any actual changes to pass previous test cases.
### Closes#7649
The bar lives alongside URL Hover in VStack at the bottom. The current
body of SurfaceView is becoming rather long and complicated, so this pr
also contains some refactors:
- Move URL Hover to a separate file
> The text is copied from previous input string to keep it consistent,
also I’m confused with text on GTK so this is my first choice, but it
can be changed as the same as GTK.
Separate prs will be opened for:
1. Set to Read-only after exits
2. Hide cursor when in Read-only
### Preview
https://github.com/user-attachments/assets/eb44e211-eac5-4f40-836c-4912b18dfb01
- Highlight matching text in command palette search results
- Support initials matching
- Trim query before filtering commands

The `zon2nix` binary is now compiled with Zig 0.16, but it still
produces Zig 0.15 compatible output (in fact the output is identical to
previous versions).
This mode allows programs to modify the code that the `backspace` key
(backarrow key in DEC parlance) sends. If this mode is
`off`/`false`/`reset` (the default, the same as before this PR), we send
the byte `0x7f`. If this mode is `on`/`true`/`set` we send the byte
`0x08`.

Extend String.matchedIndices(for:) to fall back to initials
matching when no substring match is found. Typing the first letter
of each word now matches commands, e.g. "tbo" matches "Toggle
Background Opacity", with each matched initial highlighted.

Add String.matchedIndices(for:) to find substring matches and use
it to bold and tint matched characters with the accent color in
both titles and subtitles. Title matches take priority — subtitles
are only highlighted when the title didn't match.
