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.
