souvlaki's Windows backend does config.hwnd.expect() at
platform/windows/mod.rs:57, so the None we passed was a panic inside a
tokio task on the first session, not the Err the match was written for.
The comment on that field claimed init would merely fail; it was read from
the comment, not the mechanism. No HWND is wired yet, so spawn() bows out
on Windows and the body moves to spawn_native, which is compiled out
there. Phase A ships without media keys and says so.
The offline-folder opener spawned xdg-open on every non-macOS host,
Windows included, where it does not exist. Route it through the open crate
like the other eleven sites in this crate; Linux and macOS reach the same
two binaries as before.
