On Windows, Zig's built-in libc and MSVC's CRT maintain separate
heaps, so calling free() on memory allocated by the library causes
undefined behavior. Add ghostty_free() that frees through the same
allocator that performed the allocation, making it safe on all
platforms.
Update format_alloc docs and all examples to use ghostty_free()
instead of free().

Expose both shared and static libraries as separate CMake imported
targets (ghostty-vt and ghostty-vt-static) rather than toggling
between them with BUILD_SHARED_LIBS. The zig build already produces
both in a single invocation, so both are always available.
The find_package config template is updated to export both targets
as ghostty-vt::ghostty-vt and ghostty-vt::ghostty-vt-static.
Add a c-vt-cmake-static example that demonstrates linking the static
library via FetchContent with -Dsimd=false to avoid C++ runtime
dependencies.
