The codec keeps dynamic-block, associative and material records intact on
DWG save (strict readers rejected re-saved drawings at BLOCKSCALEACTION,
associative action bodies and MATERIAL records). A checker material
texture no longer rewrites the native map source, so a map with a
procedural texture counts as content whatever its source says.
Valuable parts of #1671 (with opencadcodec#100): measured on 235 sample
drawings re-saved after an edit, a strict reader now rejects 4 instead
of 7; the remaining 4 are R14/R2000 tables, which the PR codec also
fails.

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.

Route model, paper, viewport and nested block content through one traversal while preserving leaf renderers. Carry decoded material state into mesh shading and harden solid geometry conversion.
