Adds test coverage for bitmap font rendering in the FreeType backend
using the Spleen 8x16 font in three formats:
- BDF (Bitmap Distribution Format)
- PCF (Portable Compiled Format)
- OTB (OpenType Bitmap)
Tests validate glyph dimensions and pixel-perfect rendering against
expected patterns, following the model established by the existing
TerminusTTF test.
Spleen was chosen because it ships in all three required formats from a
single source, providing consistent test data across formats. Its BSD
2-Clause license is compatible with the existing font licenses in the
repo (OFL, MIT). No existing embedded fonts could be used since they are
all TTF/OTF files that use the TrueType loader rather than the
BDF/PCF/OTB loaders being tested.
Addresses #8524.

The "unimplemented OSC command" warning is a frequent source of red
herrings as there are many OSCs that we parse but deliberately do not
implement. It's also a small drag on performance due to the function
call overhead and the overhead of formatting and outputting the message.
This PR lowers the message from warning to debug. Debug logs are
compiled out of release builds so there should be less confusion from
general users who will no longer see the message.

This fixes the Windows build failure discussed in
https://github.com/ghostty-org/ghostty/discussions/10148
When building on Windows, `symbols-unigen` and `props-unigen` crash with
`error.FileTooBig` because `stdout.end()` calls `setEndPos()` to
truncate the output. Windows does not support `SetEndOfFile` on pipes or
console handles - it returns `ERROR_INVALID_PARAMETER`, which Zig maps
to `error.FileTooBig`.
Using `flush()` instead of `end()` is correct here because:
1. `end()` flushes AND truncates - useful when overwriting files that
might have leftover content
2. For stdout captured as a pipe, there's nothing to truncate - we're
writing sequentially to a fresh pipe
3. `flush()` ensures all buffered data is sent, which is all that's
needed
CI before fix was failing with FileTooBig, after fix builds
successfully:

This PR simplifies and corrects the logic for placing a glyph
vertically, by using the `position.y` from `CoreText` directly, instead
of using an offset from the cell's starting `y`. The logic was incorrect
from the beginning, always treating the first glyph of a cell as being
at `y` of zero. We only need to be subtracting the cell's starting `x`
to align the glyphs to the cell grid.
Enabling the commented out logging, I found no instances of `position.y
differs from old offset.y` lines with `JetBrains Mono` with ligatures
turned on, but running
[ttylang](https://github.com/jacobsandlund/ttylang) (printing the
Universal Declaration of Human Rights in various languages) revealed 676
instances of this, with many only slightly off.
An example log from some Tai Tham text is the following, and this PR
adds a test based on this:
```
...pos=(0.00,-8.21) run_offset=(69.41,-8.21) cell_offset=(69.41,-8.21) old offset.y=0.00 cps = \u{1a49}\u{1a60} \u{1a3f}▸\u{1a69} \u{1a2f} → ᩉ᩠ᨿᩩᨯ

Since this is a ligature of two different grapheme clusters, Ghostty
ends up subtracting too much of the `x` value with the `cell_offset.x`
(starting x), so neither of the screenshots above are correct, but the
second is closer and gets the `y` value right.
AI disclaimer: I didn't use AI for the code, but did ask it about this
Tai Tham text and why it wasn't a single grapheme cluster:

Gtk implementation of #9945. Fixes#9948.
This adds session search to the command palette on Gtk, allowing you to
jump to any surface by title or working directory. The main difference
to the Mac OS implementation is that tabs do not have colors by which to
search.
The VT formatter was treating cells without text as blank and emitting
them as plain spaces, losing any background color styling. This caused
TUIs like htop to lose their background colors when rehydrating terminal
state (e.g., after detach/reattach in zmx).
For styled formats (VT/HTML), cells with background colors or style_id
are now emitted with proper SGR sequences and a space character instead
of being accumulated as unstyled blanks.
Adds handling for bg_color_palette and bg_color_rgb content tags which
were previously unreachable.

On main, after rearranging panes, the window becomes permanently
immovable. Grab handles temporarily set `window.isMovable = false` on
hover to prevent window dragging from interfering with pane drags
(fixing [#10110](https://github.com/ghostty-org/ghostty/issues/10110)),
but the restoration logic failed when views were destroyed during pane
rearrangement (which happens each time a pane is rearranged).
The previous approach managed `window.isMovable` state across the view
lifecycle:
1. `mouseEntered` → saved and disabled `window.isMovable`
2. View removed during rearrangement → `mouseExited` never fired
3. `deinit` ran with `self.window` already nil → restoration failed
4. Window stuck with `isMovable = false`
Instead of managing window state, prevent the mouseDown event from
reaching the window's drag handler by overriding mouse event handling in
the grab handle view.
Per [Apple's Event Handling
Guide](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/EventOverview/HandlingMouseEvents/HandlingMouseEvents.html):
> Custom NSView objects should not invoke super in their implementations
of NSResponder mouse-event-handling methods such as mouseDown:,
mouseDragged: and mouseUp: unless it is known that the inherited
implementation provides some needed functionality.
This eliminates all state management while solving both the original
issue (#10110) and the new bug.
AI disclosure: claude code found and wrote the fix. I tested it manually
to see that it works. I pressed claude quite hard here to come up with
the best fix, and looked at documentation to understand what the fix was
doing. It seems like this is a better approach overall to preventing the
main window from being dragged when grabbing the Surface Drag handle.
