iris-ai ea1f836bf9 Say the environment once, and stop a hint read going uncounted
The eleventh sweep, over the built-in bounds work in 2ac0843.

`Painter::size_hint` refused to answer for a bounded widget by returning
above the diagnostics, so that read was neither a hint hit nor a miss and
`hint_read` recorded nothing. It is a miss now, with the reason on it.

The two `for axis in Axis::BOTH` loops that `draw_widget` grew, both
writing `own_holds`, are one loop, and the comment about combining the
ask's holds no longer sits between a comment and the code it describes.

`Declared::from_axes` lost its only caller with `Widgets::declared_lens`;
`Bounds::from_axes` and `SizeRule::declared` never had one.

The scenario shrinker printed a rule with derived `Debug`, which is 130
characters an axis in a line that carries every ancestor, in the one
function whose job is output a tree can be rebuilt from. It prints its
parts again.

`bounds_cost` invented three environment-reading spellings where four
copies of one `env` helper already existed; there is now one, in
`tests/rig`, and the four copies are gone. It also verified 128 regions
inside its measured loop, which the other rigs deliberately do before
theirs; that measured 0.65% of the total, and none of it is layout.

The 250-window row with a 300 cap was built by two tests, and the one
that still explained itself tested less; they are one. The half of
`a_cap_attribute_narrows_the_widgets_box` that the wrapper's removal left
without its deciding assertion is the allocator's path instead, which
nothing at the root covered.

Format, workspace clippy under -D warnings with and without
layout-diagnostics, 206 ordinary and 210 diagnostic tests, 400 depth-5
trees warm against cold in 64.19s, and the cold dump byte-identical to
2ac0843 across all 34,986 boxes.
