A single edge's blend no longer needs a plane square to the edge at each end. Straight edges: each rail ends where it reaches the end face's surface, the side edges there are shortened or continued along their line or circle, and the blend ends where its cylinder or chamfer plane meets that surface (a fitted curve checked against both). A chamfer may end across two faces. Curved edges: at a slanted or curved end the rolling ball runs on past the end and the strip is cut back where it meets that face. A straight edge running smoothly into a bend or rounded corner is blended along its whole smooth chain. Rolling-ball fixes: smooth chains follow edges stored against their curve, the ball touches only the faces of the edges it rolls along, the seam normal at a joint comes from the face there, and each strip is fitted with neighbouring sections at its own spacing.
Action matrix: edge.fillet 83.6% -> 93.0%, edge.chamfer 82.6% -> 93.3% (697 new passes, no regressions); reference tests 76/76.

`fit: reduce` acts only on refusals marked too large. Three kinds weren't:
the corner build's contact lines leaving their faces or running backwards,
and a curved chain's contact reaching past the end of the seam it trims. Two
more were hidden: a later edge's too-large refusal lost to an earlier edge's
other error, and the corner build's lost to the local blend's in `fillet`.
The messages are unchanged.

* fix: fillet fit review follow-ups
From the review of #388 (merged before these landed):
- The Fillet dialog's Applied Radius showed nothing when editing a fillet
that was already reduced: the preview found the radius by diffing the
states before and after. The engine's preview now keeps the command
replies, and the dialog reads the radius of the feature they name.
- Pattern copies of a reduced fillet try the radius the original was
reduced to first, instead of each searching again (up to 16 fillets).
- fit: reduce with a chord or variable radius is refused instead of being
silently ignored.
- One helper appends a note to a feature's warning; too_large is imported
like unsupported in the loop and curve blends.

* feat(kernel): typed TooLarge refusal and fillet_max search
Blend refusals caused only by the size (larger than the neighbouring faces,
taller than the walls, longer than the next edge, larger than a corner
radius) now return KernelError::TooLarge, displayed as before. fillet_max
finds the largest radius below a request at which the fillet of the edges
works, to three significant digits, by building candidates; it is an explicit
call (up to 16 fillets), not run on every refusal.
A corner edge that doesn't run square to the edge is now reported as such
instead of as a blend larger than the neighbouring faces.

* feat: fillet fit option reduces a radius too large for its edges
solid.fillet takes fit: exact (the default, as before: a radius too large
for the geometry around the edges is refused) or reduce: the radius is
reduced to the largest that works for all the picked edges (kernel
fillet_max, three significant digits, every candidate built). The feature
stores the requested radius, so it refits on every evaluation; when it
reduces, the feature's warning says so and the command returns
radius_applied. Pattern copies of the fillet use the same rule. The file
format writes fit only when it is reduce.
The Fillet dialog gets a Radius Fit row (Exact / Reduce to Fit, constant
radius) and, when the preview reduced the radius, an Applied Radius line;
editing the feature keeps the choice.
One radius for all edges for now; per-edge radii and taper follow.

Fillets (local, loop, rolling ball, corner, variable, chord), chamfers
(cutters, local corners, loops, two sides), shell, draft, offset faces,
split face/body, delete face, patch/copy/stitch/trim/extend and
transforms record their history over [body] while they build: faces
rebuilt from the body's, blends in place of edges (corner patches in
place of the edges at the corner), shell walls as offsets, edges as
pieces of the body's or where two faces meet. Multi-step operations
compose each step. The push-face offset fallback now has history, and
the bore union composes its narrowed tool.
A reflection reorders a body's edges, so transforms now match edges by
identity (mirrored copies reported the wrong edges).

* Fillets along a straight edge between two cylinders: the rolling-ball blend trims curved cap edges to its contacts
The edge where two overlapping extruded arcs meet is a straight line between two cylinders
ending on planar caps. The rolling-ball blend built its sections and surface, but only
straight seams could be shortened to the contacts, so a circular cap edge was refused with
"a curved edge where the blend ends". Curved seams now keep the part of their curve between
the new ends, found from the nearest of a few samples (a search from the far end of a long
arc can settle on the opposite side of the circle).
The ball's surface projections start from each face's last answer instead of a cold search,
falling back to one when the warm answer leaves the surface's parameters or is farther than
the last point: about 4.5x faster per fillet (370 -> 80 ms), so dragging the radius is usable.

* Curve blend: refuse a closed curved seam where the blend ends
A seam that starts and ends at the same vertex (a full circle) has no
"between" two contacts, so trimming it built a broken edge. Return
"not supported yet" instead. The curved-seam trim moves into
trim_curved_seam so it can be tested directly.
