 * The dev hot-swap loop: while BRIDGE_HOT_SWAP_ENABLED is set and
 * BRIDGE_HOT_SWAP_WATCH points at the built dispatcher bundle, push the bundle
 * to the extension whenever (a) the extension (re)connects with a different
 * build than the one on disk — e.g. after an EasyEDA restart it comes back
 * with the stale baked dispatcher — or (b) the bundle file changes on disk
 * (the extension build:watch rebuilt it). Combined with `tsx watch` for the
 * server this closes the edit → run loop without any .eext re-import.
