docs(ecosystem): add pipeline position, typed-wasm + nextgen-typing relationships

- Position in katagoria → typell → typed-wasm → PanLL pipeline
- typed-wasm: aggregate-library (shared WasmGC binary layout conventions)
- typell: type-theory-foundation (typell-affinescript bridge crate)
- nextgen-typing: coordination-parent
- ephapax: sibling-wasm-target
- katagoria: research-upstream
