* fix(build): scope Kotlin bridge to linked Maven modules
* fix(run): resolve nested Go modules for context runs
* fix(gradle): discover nested builds and select compatible JVMs
* fix(workspace): share project discovery and module ownership
* fix(run): keep root toolchains for nested modules and resolve them once per module
- Python run configurations of a nested module without its own virtualenv use the closest one up to the project root.
- Gradle builds and runs fall back to the JDK matching the project's Java version when the Gradle version is unknown.
- Module-local interpreters and toolchains are resolved lazily, once per owning module.
- Tests build expected paths per segment so they hold on Windows.
