d2efa707 fixed projects-store detection via __VSCODE_CONFIG__, but
lib/desktop.isVSCodeRuntime (used by useDirectoryStore) still required
RuntimeAPIs. At webview startup that left directory init on stale
localStorage paths from other windows (#2359).
Share bootstrap detection in lib/vscodeBootstrap and use it from both
desktop runtime checks and the projects-store helper.
