Moves snapshot capture entirely into the apitrace retrace layer (glReadPixels + PNG encode). Drops the MOBILEGL_PRESENT_DUMP_PATH / MOBILEGL_PRESENT_STATS / MOBILEGL_PRESENT_DUMP_CALL / MOBILEGL_PRESENT_CURRENT_CALL / MOBILEGL_TRACE_CURRENT_CALL_OVERRIDE plumbing from Config, ConfigLoader, VulkanRenderer (GetPresentedDumpPixel/WritePresentedDumpPpm + present-stats readback), the EGL/GLX/Android ws shims, and the Android trace_replay_core PPM reader.
DirectVulkan ReadPixels on the default framebuffer now remaps raw swapchain pixels (top-left origin, preTransform-rotated) to GL orientation (bottom-left origin) so the retrace snapshot matches the golden; SwapchainObject also resizes the default-FBO stencil attachment to the swapchain extent to fix GL_INVALID_FRAMEBUFFER_OPERATION under the glReadPixels completeness check.
Registration now documents the trace_cases.json registry (the CMakeLists /
apk.yml instructions were stale). Adds the field-tested guidance from
authoring the Create fixtures: in-tree apitrace fork requirements (frametrim
DSA/multi-bind, persistent-map shadowing) and the Windows wgltrace wrapper,
frozen-world + unfocused-window capture discipline, late-frame selection,
trim verification, brotli repack (with the stale-archive trap), golden
content verification, Android signing/stale-package/emulator-flake and
stale-result pitfalls.

Two 1.21.1 NeoForge Create in-world captures facing water wheels and a
large cogwheel, one per flywheel backend (/flywheel backend indirect and
instanced). The indirect trace exercises the compute scatter/cull
pipeline, glMultiDrawElementsIndirect with GPU-written commands, and
draw-parameter emulation; captured with persistent-map shadowing so the
unflushed scatter descriptors Flywheel writes are recorded. Both trimmed
to a single frame and brotli-repacked (~7 MiB each).

- compare actual output against primary and alternate golden images
- record the matched golden path in trace replay results
- allow APK and Linux retrace fixtures to pass alternate golden paths
- keep nostalgia validation accepting both Mesa and PC goldens
