Subject: [PATCH] Fix undefined parsing error on languages missing from call
 routers (#364)

* fix: mapping all supported languages to callRouters to fix undefined apply error (#352)

* fix(cli): remove duplicate Swift/Kotlin keys in callRouters causing TS1117

* refactor: remove runtime callRouter fallbacks, rely on Record<SupportedLanguages> compile-time enforcement

* refactor: use 'satisfies' keyword for callRouters compile-time enforcement
