First real GPU implementation. Ring/PM4 frontend (ring_view,
ring_drain, pm4) drains the command processor; gpu_system owns the
threaded backend (DrainFence RPC + parker/fence helpers from M1) and
the MMIO-mapped register block (mmio_region).
Xenos shader frontend: ucode/{alu,control_flow,fetch,mod}.rs decode
the Xbox 360 microcode, translator.rs lowers it onto the WGSL
xenos_interp interpreter shader (shaders/xenos_interp.wgsl).
shader_metrics.rs counts decode/translate work.
Render state: draw_state, primitive, render_target_cache,
texture_cache, tiled_address (Xenos's swizzled tiled-memory layout),
xenos_constants (register field constants), edram (the 10 MiB EDRAM
model with MSAA), and resolve.rs (TILE_FLUSH copy-out — clear-resolve
plus bitwise-equivalent 32 bpp + 64 bpp paths landed). handle.rs
owns the typed GPU-resource handles the kernel hands out.
