The one-time SQLite→PostgreSQL migration runs inside createTaskStoreForBackend
before any HTTP server listens, so browsers saw "connection refused" and open
tabs failed silently for minutes. Now:
- CLI: a temporary holding server binds the dashboard port for the boot window,
serving an auto-reloading "Database migration in progress" page and an
/api/health payload with status "migrating" + structured progress; the port
is handed off (awaited) to the real app.listen().
- Dashboard SPA: already-open tabs render the new MigrationInProgressBanner
from the 15s health poll when status is "migrating".
- Desktop: LocalRuntimeManager publishes migration progress on
DesktopRuntimeStatus via the new core onMigrationProgress option;
DesktopLaunchGate shows the live label and extends its 30s startup timeout
while progress advances (2min stall cap), in both boot and first-run flows.
