NJ-6: full solution builds 0/0; feature-targeted tests green (Commons codec 38,
TemplateEngine InstanceService 17, ConfigDB normalizer 8, Transport serializer 12,
SiteRuntime InstanceActor 47). Component-Commons now describes the native-typed
List encoding + read-both decode + the three normalization paths. #93/M3 folded in.
Encode emits native-typed JSON ([10,20], [true,false], ISO dates); Decode reads
both old (array-of-strings) and new forms. Existing data normalized via an
idempotent central MS SQL startup normalizer, active site SQLite normalization in
the InstanceActor override-load path, and normalize-on-import for bundles.
Approved via brainstorming (Approach B, thorough).
