JOIN previously only merged collinear lines or co-circular arcs into a
single Line/Arc and rejected everything else as "not co-linear" — so the
segments of a broken polyline, which meet at vertices but run at angles,
could never rejoin. It also flattened endpoints to the first segment's Z,
silently discarding height.
Rewrite the geometry pass to chain segments wherever their endpoints
touch, regardless of angle: a collinear straight run still collapses to
one Line, a planar chain becomes an LwPolyline (arcs carried as bulges),
and a chain with varying Z becomes a Polyline3D, preserving height.
Open/closed is detected from the endpoints; a selection that isn't a
single connected chain, or holds an unsupported entity / tilted arc, is
refused with a clearer message.

Remove accidental dead code (unused imports, the superseded paste tool()
helper, a never-read TORIENT handles field, a duplicate let binding, an
unneeded mut) and mark intentional-but-unwired scaffolding with
allow(dead_code): the web-only save_to_bytes, the plugin loadable() probe,
the planned PICK_HIGHLIGHT colours, the DynFieldSpec label, and the layout
ribbon helpers. Native build is now warning-clean apart from the upstream
nom/quick-xml future-incompat notices.

The Home tab was already titled "Draw"; rename the module to match:
folder modules/home → modules/draw, HomeModule → DrawModule, id "home"
→ "draw". The inner draw/ command folder is kept (modules::draw::draw).
Update build.rs PRIORITY ("home" → "draw") so the tab returns to the
front of the ribbon; registry.rs regenerates accordingly.
