Swift conveniently converts strings to UTF-8 encoded cstrings when
passing them to external functions, however our libghostty functions
also take a length and we were using String.count for that, which
returns the number of _characters_ not the byte length, which caused
searches with multi-byte characters to get truncated.
I went ahead and changed _all_ invocations that pass a string length to
use the utf-8 byte length even if the string is comptime-known and all
ASCII, just so that it's proper and if someone copies one of the calls
in the future for user-inputted data they don't reproduce this bug.

Move the search result counter inside the search text field using an
overlay, preventing layout shift when results appear.
**Before:** The counter appeared as a separate element in the HStack,
causing the text field to shift when results loaded.
**After:** The counter is overlaid inside the text field on the right
side with reserved padding, eliminating layout shift.

#189 for macOS
This adds a search GUI for macOS, including macOS-standard menu bar
items, and keybindings that match other native macOS applications such
as Terminal app, Safari, and others. This introduces a new keybinding
action `start_search` to start a blank search for GUIs.
This PR also resolves a number of minor issues found in the search
subsystem and renderer related to search from prior PRs. This should
result in overall improved search stability. **Please note there are
still known issues (bottom of this PR).**

feature, and I'm excited

point of tip releases:

getting in the way of reading the terminal.
## Known Issues
TODO prior to this PR merging:
- [x] Single-byte search terms cause a crash since our sliding window
can't handle it. This PR temporarily requires search terms with length
2+ before starting a search to avoid it. 😄
- [x] The way `ScreenSearch` prunes history is fundamental unsafe. With
a rapidly growing screen that could reach history limits and an active
search at the same time, Ghostty is almost guaranteed to crash
currently. The workaround is to not search actively scrolling screens
(new data) for now.
- ScreenSearch has to restart on resize. We don't have any good way to
handle reflow since our search results are unpinned. We can look into
this later but this fixes correctness.
- PageList now tracks serial number by node that monotonically increases
on any alloc or reuse. Our screen search uses this to prune invalid
history results.
