Only the lines this branch added lose their comments; the commits before
keep them, with the reasoning behind each change, for whoever digs into
that code later.

A V# with records but a base address of 0 threw at bind time ("null shader
buffer descriptor address"), although a shader that never reaches that slot
works on hardware; an access through it would fault there, so a working
title does not make one.
Such a V# is specialized empty like one without records (every access out of
bounds) and binds the placeholder buffer; the draw cache's alias check skips
it as the build does. The tests expecting the old rejections are dropped.

A V# without records (all zero, say, for a slot the taken path never
uses) makes every access out of bounds on hardware: loads read zero or the
format's default, stores and atomics are dropped. The recompiler now
specializes such a buffer as empty, so every access through it is out of
bounds, and the driver binds a small per-device placeholder buffer to the
element instead of rejecting the V#. A V# with records at address zero
still throws.

A sampled T# of a 32-bit integer format over a depth layout (a Z swizzle
mode) reads the raw bits of a depth plane, and a host cannot view a depth
image with an integer format. Such an image is specialized as float and
bound as the depth surface's float view: a fetch returns the same bits,
which the shader keeps as they are, and swizzle constants read as the
integers 0 and 1. Filtering is forced to point, as for integer formats.
The same T# over guest memory rather than a depth surface throws.

Dispatch cache with per-key value variants and data-only hits (flat-SRT leaves the recompiler
proves pure are refreshed into the resource template instead of re-captured), dispatch and draw
recipes replaying a proven prepare, register-keyed draw entries, template data refresh, unit
shadows in device-local slabs, 64 KiB block-unit storage tracking with windowed detile, DCC
clear-key proofs, per-class GPU timing, a CPU copy path with batch read tracking, present slot
ring, rate-limited reaps and lazy completion counting, plan-failure and poisoned source memos,
bindless image tables (runtime-indexed descriptor arrays from a CPU-read table) so the
per-frame compute program that failed its plan now compiles. Worker affinity opt-in, per-draw
logs behind APS5_TRACE_DRAWS, wait-timeout reports include the recorder's view of the label.
Fixes a use-after-free behind BDA-miss dispatch snapshots and the CPU-write stamp of
UnchangedSinceCollected. Intro-video stage: 154 -> ~500 presents per 10 s at 4K.
