Extension point so private/unsupported platforms can plug in their own implementations of the kernel/libc primitives Tracy depends on, without patching the `#if`/`#elif` chains. Projects supply a platform header via `-DTRACY_PLATFORM_HEADER="\"my_platform.h\""` at build time. Tracy includes it in any TU that needs the hooks. The header toggles per-category `TRACY_HAS_CUSTOM_*` macros and declares matching `tracy::Platform*` functions. Available hooks: - `TRACY_HAS_CUSTOM_THREAD_ID` → `PlatformGetThreadId` - `TRACY_HAS_CUSTOM_USER_INFO` → `PlatformGetHostname`, `PlatformGetUserLogin`, `PlatformGetUserFullName` - `TRACY_HAS_CUSTOM_SAFE_COPY` → `PlatformSafeMemcpy` - `TRACY_HAS_CUSTOM_ALLOCATOR` → `PlatformMalloc`, `PlatformFree`, `PlatformRealloc`, `PlatformAllocatorInit`, `PlatformAllocatorThreadInit`, `PlatformAllocatorFinalize`, `PlatformAllocatorThreadFinalize` Each hook is wired as the first arm of its respective `#if`/`#elif` chain, so existing supported platforms are unaffected. Template files in `examples/CustomPlatform/` and a new subsection in `manual/tracy.tex` document the mechanism.
