Fix BT reconnect and clipboard woes

+### 7. Laptop (Windows) — experimental
+
+There is no Windows installer yet. The app is **cross-built from Linux**: if
+you already build the Linux app on this machine, one more script produces the
+Windows `.exe` from the same checkout.
+
+```bash
+./install_windows.sh                 # toolchain + vortex-ui-tauri.exe
+./install_windows.sh --installer     # also an NSIS setup.exe
+```
+
+It installs what is missing (clang/lld/llvm, the `x86_64-pc-windows-msvc` Rust
+target, `cargo-xwin`, node) and builds. The first run additionally downloads
+Microsoft's CRT and Windows SDK — a few hundred MB, once, into
+`~/.cache/cargo-xwin`; `cargo-xwin` accepts Microsoft's licence for that
+download on your behalf, so build on Windows instead if you would rather not.
+The result lands in
+`linux/ui-tauri/src-tauri/target/x86_64-pc-windows-msvc/release/`.
+
+Copy the `.exe` to the Windows machine and run it — there is nothing to
+install, it sits in the tray like the Linux build, and pairing is the same BLE
+flow from the same phone app.
+
+**What works:** pairing, reconnect, notification mirroring, clipboard, file
+transfer, Universal Control.
+
+**What does not:** screen mirror/cast, the continuity camera and the earbuds
+hand-off. Those are GStreamer/GTK/PulseAudio/BlueZ and have no Windows
+implementation, so they are compiled out rather than shipped broken.
+
+**Two things to expect on first run.** The binary is unsigned, so SmartScreen
+warns — *More info → Run anyway*. And on Windows 10 the window can open blank:
+that is a missing **WebView2 runtime** (Windows 11 ships it). Install
+Microsoft's Evergreen WebView2 Runtime and relaunch.
+
+> ⚠ **Experimental, and less tested than Linux.** The BLE layer here is a
+> separate implementation against a platform seam (WinRT rather than BlueZ),
+> and it has had far less real-world use. Treat it as a preview and please
