* [Fix] record each resource's root namespace instead of re-deriving it

* [Update] build each scope's name-resolution index on first probe

* doc guideline

* remove integration flag

* [Add] Arrowhead Framework Example to textual-notation validation corpus

Registers AHFNorwayTopics as a validation test case, alongside its
AHFCoreLib/AHFProfileLib library dependencies which supply imports but
have no round-trip baseline of their own.

* [Add] GrammarUnreachable attribute for grammar-dead textual-notation rules

Computes reachability from RootNamespace over the merged KerML+SysML
KEBNF grammar (SysML definitions override same-named KerML ones) and
decorates every generated Build{Rule} method whose production has no
incoming reference with [GrammarUnreachable], so a HandCoded companion
that turns out to still call it stays consistent by explicit exclusion.

* [Add] Five pilot-implementation examples to textual-notation validation corpus

Redefinition, Generalization, Flow Usage, Binding Connectors, and
Interface examples, converted from the SysML v2 pilot implementation's
training corpus via its own SysML2XMI tool. Each closes coverage gaps
on grammar-reachable rules (Redefinition, Subclassification, Flow,
BindingConnector, binary Connector) identified as exercised by no
existing test case. Expected/*.sysml baselines are the writer's own
captured output, not the pilot's literal source text, since the two
differ only in the documented ACCEPT categories (redefines/:>> and
specializes/:> keyword aliases, formatting) per CLAUDE.md.

PortExample.sysmlx is a shared library dependency for three of the
five (Flow Usage, Binding Connectors, Interface), following the same
no-baseline-of-its-own pattern as AHFCoreLib/AHFProfileLib.
