Steps 309-319: Sprint 11 Phases 11d-e — Kotlin/C# languages + workflow annotation foundation

Phase 11d (Steps 309-313): Kotlin + C# parsers and generators
- KotlinParser (regex-based): fun, suspend fun, class, data class, val/var
- KotlinGenerator: idiomatic Kotlin output with type mappings
- CSharpParser (regex-based): methods, async, class, interface
- CSharpGenerator: Allman braces, foreach, Task async, LINQ types
- Pipeline integration for both languages, 10 parsers + 10 generators

Phase 11e (Steps 314-319): Workflow annotation foundation
- AnnotationInference: generalized multi-subject inference engine
- Subject 9 routing annotations: ContextWidth, Review, Ambiguity,
  Automatability, Priority, ImplementationStatus
- SkeletonAST: project specification before code exists
- Architect tooling: createSkeleton, addSkeletonNode, getProjectModel,
  inferAnnotations RPCs + 4 MCP tools (42+ total)
- Inference-to-routing bridge: complexity→ambiguity, getter→deterministic
- TrainingDataExporter + TrainingDataGenerator scaffolding
