Function: attachRoutePatchMiddleware()
attachRoutePatchMiddleware(
app):void
Patches around @mastra/express’s custom-route dispatcher so the
plugin’s custom API routes (e.g. historyRoute) work when
MastraServer is hosted on an Express subapp mounted under a parent
path (e.g. /api/mastra).
The adapter’s registerCustomApiRoutes matches against req.path
(mount-relative, correct) but dispatches to its internal Hono
mini-app using req.originalUrl, which still contains the parent
mount prefix. The Hono app registers the literal route paths
(for example /route/history), so the absolute URL never matches
until we overwrite originalUrl for /route and /route/* to the
mount-relative path.
