Pull request overview

This PR replaces usages of IntelliJ-platform VfsUtil/VfsUtilCore and the old IDEA FileUtil implementation with Consulo’s VirtualFileUtil and consulo.util.io.FileUtil, reducing reliance on consulo.ide.impl.idea.* internals and aligning file/VFS access with the Consulo API.

Changes:

• Replaced VfsUtil.loadText / VfsUtilCore.getRelativePath / VfsUtilCore.visitChildrenRecursively with VirtualFileUtil equivalents across production and test code.
• Replaced IDEA FileUtil.copy/ensureCanCreateFile calls with consulo.util.io.FileUtil (including explicit permission copier for file copy on Windows).
• Minor related API alignment: ApplicationManager.getApplication() → Application.get(), SystemInfo.isWindows → Platform.current().os().isWindows(), and bundle message → PyLocalize.
