docs: mark native-typed JSON feature complete; update Component-Commons codec note

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.

 # Native-Typed JSON for List Attribute Values — Design
 
 **Date:** 2026-06-16
-**Status:** Approved (brainstorming) — ready for implementation plan
+**Status:** Implemented (NJ-1 … NJ-6, branch `feature/native-typed-json`) — full solution builds 0/0; feature-targeted tests green across Commons, TemplateEngine, ConfigurationDatabase, SiteRuntime, and Transport. Follow-up **#93/M3** (populate `InstanceAttributeOverride.ElementDataType` on write) was folded into NJ-2 so the central normalizer can read the override element type directly.
 **Branch:** `feature/native-typed-json`

 Commons must define shared primitive and utility types used across multiple components, including but not limited to:
 
-- **`DataType` enum**: Enumerates the data types supported by the system: Boolean, Int32, Float, Double, String, DateTime, Binary, and **List** (a homogeneous multi-value attribute). A `List` attribute carries a companion `ElementDataType` (one of the scalar types — String, Int32, Float, Double, Boolean, DateTime; not Binary, not nested List) on `TemplateAttribute` / `InstanceAttributeOverride` and the flattened `ResolvedAttribute`. List values are stored and transmitted as a canonical JSON array via the `AttributeValueCodec` helper (scalars keep their historical invariant-culture string form); the `ElementDataType` is fixed by the defining level and cannot be changed on a derived template or instance override.
+- **`DataType` enum**: Enumerates the data types supported by the system: Boolean, Int32, Float, Double, String, DateTime, Binary, and **List** (a homogeneous multi-value attribute). A `List` attribute carries a companion `ElementDataType` (one of the scalar types — String, Int32, Float, Double, Boolean, DateTime; not Binary, not nested List) on `TemplateAttribute` / `InstanceAttributeOverride` and the flattened `ResolvedAttribute`. List values are stored and transmitted as a canonical **native-typed** JSON array via the `AttributeValueCodec` helper — numbers and booleans unquoted, strings quoted, `DateTime` as ISO-8601 (e.g. `[10,20]`, `[true,false]`, `["2026-06-16T00:00:00Z"]`); scalars keep their historical invariant-culture string form. `AttributeValueCodec.Decode` is backward compatible: it reads both the native form and the earlier array-of-strings form (`["10","20"]`). Already-persisted old-form values are normalized to native on the fly — an idempotent central startup normalizer (`ListValueNormalizer`, run after migrations) rewrites MS SQL rows, the `InstanceActor` re-persists site SQLite overrides on load, and bundle import re-encodes List values. The `ElementDataType` is fixed by the defining level and cannot be changed on a derived template or instance override.
 - **`RetryPolicy`**: A record or immutable class describing retry behavior (max retries, fixed delay between retries).
 - **`Result<T>`**: A discriminated result type that represents either a success value or an error, enabling consistent error handling across component boundaries without exceptions.
 - **`InstanceState` enum**: Enabled, Disabled.
