Jon Parise os: use GetTempPathW for allocTmpDir on Windows 3mo ago

terminal/kitty: unit tests for unicode placements

core: add new OSC parser This replaces the OSC parser with one that only uses a state machine to determine which OSC is being handled, rather than parsing the whole OSC. Once the OSC command is determined the remainder of the data is stored in a buffer until the terminator is found. The data is then parsed to determine the final OSC command.

terminal/kitty: add loading limits to kitty graphics protocol Add a Limits type to LoadingImage that controls which transmission mediums (file, temporary_file, shared_memory) are allowed when loading images. This defaults to "direct" (most restrictive) on ImageStorage and is set to "all" by Termio, allowing apprt embedders like libghostty to restrict medium types for resource or security reasons. The limits are stored on ImageStorage, plumbed through Screen.Options for screen initialization and inheritance, and enforced in graphics_exec during both query and transmit. Two new Terminal methods (setKittyGraphicsSizeLimit, setKittyGraphicsLoadingLimits) centralize updating all screens, replacing the manual iteration previously done in Termio.

os: use GetTempPathW for allocTmpDir on Windows `allocTmpDir` previously read `%TMP%` via `getenvW` and returned `null` if the variable wasn't set, requiring each caller to to deal with the nullable. Unfortunately, there isn't a platform-neutral default value that makes sense for those cases (i.e. `/tmp` is POSIX-y). We now use `GetTempPathW` on Windows, which is the official way to get this directory: `TMP` → `TEMP` → `USERPROFILE` → `GetWindowsDirectoryW`. With a real system call behind it, the function no longer needs to be nullable: the only remaining failure modes are OOM (propagated) and the syscall itself failing or returning data we can't decode. In those later cases, we use `C:\Windows\Temp` as a fallback, similar to how we use `/tmp` in the POSIX case. The Windows path always allocates so it still must be paired with `freeTmpDir`, which matches the existing contract.

libghostty: add placement pixel_size and grid_size, rename calculatedSize Expose Placement.pixelSize() and Placement.gridSize() as new C API functions ghostty_kitty_graphics_placement_pixel_size() and ghostty_kitty_graphics_placement_grid_size(). Both take the placement iterator, image handle, and terminal, returning their results via out params. Rename the internal Zig method from calculatedSize to pixelSize to pair naturally with gridSize — one returns pixels, the other grid cells. Updated all callers including the renderer.

input: use std.Io.Writer for key encoder, new API, expose via libghostty This modernizes `KeyEncoder` to a new `std.Io.Writer`-based API. Additionally, instead of a single struct, it is now an `encode` function that takes a series of more focused options. This is more idiomatic Zig while also making it easier to expose via libghostty-vt. libghostty-vt also gains access to key encoding APIs.
