Add Java extension support and configure multiple JDK runtimes. Introduce a wrapped VS Code package that includes JDK 25 in the PATH to support the Red Hat Java language server. Switch from using `programs.vscode.userSettings` to a manually managed `settings.json` file via `home.file`. This allows the settings file to be writable by external tools like `kilo-code` at runtime while preserving them across Nix configuration switches by using `force = false`.
