Update Linux Windows build script to add scripts directory to PATH and reference cargo-xwin by name rather than direct path to wrapper script, improving compatibility with Tauri's runner resolution mechanism.
Add cargo-xwin wrapper script that invokes `cargo xwin` subcommand and update Linux Windows build script to use wrapper as --runner instead of cargo-xwin binary name directly. Add chmod +x to ensure wrapper is executable before build.
Update @tauri-apps/api and @tauri-apps/cli to version 2.10.1, and tauri runtime to 2.10.1 for consistency across desktop client dependencies. Update tauri-build to version 2.5.5.
Update all Windows build configurations, scripts, and documentation from i686-pc-windows-msvc (x86) to x86_64-pc-windows-msvc (x64). Update npm scripts, build-tunnel-helper.sh target validation, bundled helper paths, and tunnel manager strategy references. Add XWIN_ARCH=x86_64 environment variable to Linux cross-build command and --xwin-arch flag to cargo xwin invocation.
Change cargo-xwin detection from `command -v cargo-xwin` to `cargo xwin --version` to properly verify cargo subcommand availability on Linux systems cross-compiling to Windows targets.
Add Ubuntu-to-Windows build workflow using cargo-xwin for i686-pc-windows-msvc target. Update build-tunnel-helper.sh with host OS detection, target validation, and cargo-xwin support for Linux cross-compilation. Add tauri.windows.conf.json to configure NSIS-only bundle output and npm script for Linux-based Windows builds. Update client-platforms.md to document cross-compilation support and clarify that MSI packaging still requires Windows environment.
