modularize sdk (#208)

* Modularize SDK: migrated client and server implementations to separate modules. Removed old configuration files and reorganized the source code structure

* add support native targets and update js/wasm configurations

* Refactor sample projects: add samples as composite builds, replace hardcoded dependencies with version catalog, remove obsolete gradle wrapper files

* Update .gitignore: exclude SWE agent directories (.claude/ and .junie/)

* Refine CodeQL workflow: update Kotlin build steps to target individual modules separately instead of building all at once
