- Add root CHANGELOG.md as master index with executive release summaries
- Add dedicated changelogs for last 4 releases (v2026.38, v2026.39, v2026.40/40.1 unified, v2026.41) and unreleased
The DWG writer truncates an XRecord Chunk to u8::MAX bytes, so a sketch's
constraint set or named-parameter table silently lost every entry on the
next DWG open once serialization passed ~255 bytes (found live: a
23-constraint demo round-tripped fine through DXF but came back empty
through DWG). Split the blob across multiple same-code 310 entries on
save and reassemble them on load, entirely on the OCS side.

None of the 17 constraint commands (HCONSTRAINT, VCONSTRAINT,
PCONSTRAINT, QCONSTRAINT, ECONSTRAINT, TCONSTRAINT, NCONSTRAINT,
NRCONSTRAINT, LCONSTRAINT, FXCONSTRAINT, SYCONSTRAINT, CCONSTRAINT,
EDCONSTRAINT, CPCONSTRAINT, MPCONSTRAINT, OCCONSTRAINT, DCONSTRAINT,
ACONSTRAINT) carried an inventory::submit! registration, so they were
invisible to command-line autocomplete, the MCP commands listing, and
the ALIASEDIT shortcut editor (which rejects a custom shortcut target
that isn't in this same registry). Each constraint module now
registers itself, with a regression test pinning the full set.

Arcs are now full constraint participants (center/radius via the existing
Circle-shaped solver path, plus real endpoints kept consistent by arc-rules
CurveValue constraints); adds Diameter/DistanceX/DistanceY/ArcLength/Normal
constraint kinds and initial Ellipse entity support (center-based
constraints only). DWG-native class mappings and gaps (ArcLength, Ellipse)
are grounded against real ObjectARX headers rather than guessed, so files
saved with DWG-native constraints stay honest about what AutoCAD can
actually represent.
Also fixes a case-sensitivity bug where a lowercase named-parameter
reference typed at a dimensional constraint's value prompt was rejected
(the command line uppercases SingleToken input before the parameter-name
lookup), and adds a "Used by" column to the Named Parameters panel.
