#1511 added an orthogonal ellipse projection and a nearest-end
arc_parameter to draw/modify/geom.rs, the latter shadowing the kernel
function of the same name. Both now live in opencadkernel 237827e and
are re-exported here, so every kernel caller gets them too.
test_coincident_line_and_arc_grip_move only printed values and asserted
nothing; removed.
Pins opencadkernel 237827e, opencadgraph fe36957.

The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

EXTEND asked where a line reaches by matching over every Geo variant and
running its own line-line, line-circle and line-ellipse test — twice
over, once for a LINE and once for a polyline's terminal segment, about
two hundred and sixty lines between them. A boundary spline was walked
as sixty-four chords there rather than intersected, so an extend landed
on the chord nearest the spline instead of on the spline.
Both are one call now: shoot the segment's own infinite line and take
the nearest crossing on the side being extended. That is `cut_params`,
which every other cut in the file already goes through.
With those two gone, the sampled copy carried beside each boundary
spline had no remaining reader, so a spline boundary is now only ever
the exact NURBS. The line-ellipse adapter lost its last caller with it.

`line_seg_ts`, `arc_seg_ts`, `ellipse_seg_ts` and `spline_seg_ts` each
walked every boundary kind and solved that pair by hand — four nested
matches over the same seven cases. They are now four descriptions of the
target as a `Curve` handed to one `cut_params`, which asks the kernel.
Their signatures are unchanged, so the twenty call sites are untouched.
Three things follow from it.
Boundary splines and target splines stop being sampled. A cut on a spline
now lands where the boundary actually crosses rather than where a fixed
sampling said it did, because the kernel subdivides and converges to a
tolerance instead.
Rays and infinite lines as boundaries are handled by the kernel's extent
rather than by a case here — a ray rejecting what lies behind its origin
is the kernel's job now.
`extend_spline` shoots a real ray. It used to build a line a million units
long and cut against that, which both invents a limit and, at survey
coordinates, is comparable to the coordinates themselves. The ray's
direction is a unit vector, so what comes back is the distance to the
boundary. That also fixes the hit position, which multiplied by the
million-unit extent a second time and landed the extended end far past
where it was supposed to.
`cut_params` clamps to 0..=1 only for a bounded target; a ray has to keep
the parameter it comes back with, since the distance is the answer.

TRIM, FILLET and EXPLODE each carried their own copy of the same plane
maths. The copies had already drifted apart: `ll` differed only in
parameter names between trim.rs and fillet.rs, `arc_pts` only in which
angle helper it called, and `norm` meant angle normalisation in trim.rs
and explode.rs while meaning vector normalisation in two other files.
The implementations now live in cadkernel's geom2d. A new local `geom`
module adapts the call shapes — the kernel takes `[f64; 2]` points and
returns `[f64; 3]`, while these commands pass loose scalars and feed
`WireModel::points`, which is `[f32; 3]`. Narrowing stays on this side
because only the caller knows whether it is a preview wire, which leaves
`points_low` empty and accepts the loss, or resident geometry, which
splits the f64 into a high/low pair instead.
Call sites are untouched: the kernel functions are imported under the old
local names, so the signatures they were written against still hold.
This also fixes ELLIPSE trim and extend previews. `ellipse_pts` wrote its
components as [x, z, y] while `arc_pts` — reached from the same match in
`entity_pts`, feeding the same `[f32; 3]` — wrote [x, y, z], and
`WireModel::points` is documented as world-space positions. Ellipse
previews were collapsing onto y = 0 and displacing along Z. The kernel's
`ellipse_arc` orders them correctly, so delegating corrects it.
