swung0x48 7e51860435 [MG_Backend, docs] (P7): a wire decline's line says decline, not draw, because the texture rows count per sync ...

Fable review of the B3 rework, nit: MGL_WIRE_DECLINE_AT logged "Magma wire
draw declined [Site]" from every site, but the Tex*, Shape* and Upload*
rows are reached through SyncTextureResourceByHandle, whose callers are not
only the draw/dispatch texture preparation: the descriptor resolver,
framebuffer attachments, CopyTexSubImage, mipmap generation and
CopyImageSubData each Fatal right after a failed sync, and texture
readback falls back to the unbacked shadow. Those counters are per sync,
not per draw - a draw sampling three unsyncable textures counts three, a
failed attachment sync counts once and is then a Fatal.

- WireDeclineTally.h: the line is "Magma wire decline [Site]: ...", and
  the macro's comment says the texture rows are per sync and names the
  callers. Disaggregated-only header; no test or script matches the old
  text (git grep).
- magma-b3.md §1.5: says the counters are per sync and that the log lines
  quoted in §1.3 / §1.5 carry the old wording.
