* Replace SessionStateEncoder with IEncodeable on session/subscription models
- Source-gen [DataType]/[DataTypeField] on: MonitoredItemOptions, MonitoredItemState,
SubscriptionOptions, SubscriptionState (auto-generated Encode/Decode/IsEqual/Clone)
- Manual IEncodeable on: SessionOptions, SessionState, SessionConfiguration
(ConfiguredEndpoint and IUserIdentity require manual encoding)
- Delete SessionStateEncoder.cs (488 lines removed)
- Remove [DataContract]/[DataMember]/[KnownType]/[CollectionDataContract] attributes
- Remove JsonSerializerContext classes
- Change init -> set, byte[] -> ByteString, DateTime -> DateTimeUtc
- MonitoredItems: ArrayOf<MonitoredItemState> with StructureHandling.Inline
- Subscriptions: ArrayOf<SubscriptionState>
* Source generator: support partial init properties with backing fields
Add IsInitOnly detection to the [DataType] source generator so that
partial properties with init-only setters can be used in IEncodeable types.
For each init-only partial property, the generator:
- Emits a private backing field (__PropertyName)
- Emits the partial property implementation (get => __field; init => __field = value)
- Uses the backing field in Decode() instead of the property
- Skips simple init-only fields in Clone() (record 'with' already copies them)
Detection uses both IPropertySymbol.SetMethod.IsInitOnly and syntax-tree
fallback (SyntaxKind.InitAccessorDeclaration) for partial definitions.
* docs: add partial init properties and session state migration sections
- SourceGeneratedDataTypes.md: new 'Partial Init Properties' section
documenting backing field generation for init-only partial properties
- MigrationGuide.md: new 'Session State Persistence' section covering
* make most ptojects aot compatible
* Remove newtonsoft
* Migrate all projects from Mono.Options to System.CommandLine 2.0.5
* Fix array clone
* Replace serializers for storage using new attribute driven type geberator
* Add new AOT integration tests covering all functional areas
* Documentation updates
