Draw the repairs, before anything sharpens what they removed

A spot set now composes detail passes of its own, one per round, and they
go ahead of every operation's kernel. That placement is the decision worth
recording: a sharpening pass reads a neighbourhood, so sharpening a dust
mark before removing it smears its edge into pixels the repair's disc does
not cover, and what survives is a faint over-sharpened ring around an
otherwise perfect patch. It also disagrees with ARCH §5.2, which draws
spot removal after clarity — docs/spot-removal.md §5.1 is where that is
argued out.

Every length reaching the shader is in render pixels, converted here where
the framing is in scope. Both the centre and the source go through
`Framing::output_at` — the same map the fused pass applies to every pixel
— so a rotated photograph rotates the offset with no trigonometry, and the
radius is found by mapping a point one radius above the centre and
measuring, rather than by multiplying by a ratio this function has no
business knowing about. The tests turn and crop the frame and expect the
mark to stay gone, which is the property that arrangement buys.

compose_full now takes the spot set, because a photograph with a repair
and no sharpening still has a detail stage: a fused pass that encoded its
own output there would quantise twice and bind to a texture of the wrong
format. compose_detail_for takes the source size for the same kind of
reason — a RenderScale describes the region on screen, and a spot is
stored against the photograph.
