fix(routing): resolve TanStack Router file-ignore and code-split warnings

[samuv]

Change:

• Fix routeFileIgnorePattern in vite.renderer.config.ts — the pattern was matched against individual file/directory names (not full paths), so root/ with a trailing slash never matched anything. Replace with (__tests__|guards|hooks|root-error) to correctly exclude the guard utilities, hooks, and error boundary from the route tree.
• Remove export from McpOptimizerRoute, RegistryGroupDetail, and RegistryServerDetail — named exports from route files prevent TanStack Router from code-splitting those chunks.
• Update the three corresponding test files to access the component via Route.options.component instead of the now-removed named imports.

Pull request overview

Resolves TanStack Router warnings by correcting which files/directories are ignored during route-tree generation and by removing named exports from route files to allow proper auto code-splitting.

Changes:

• Fix TanStack Router routeFileIgnorePattern so non-route utilities under routes/ are excluded from route generation.
• Remove named exports of route components from three route files to unblock TanStack Router chunk code-splitting.
• Update affected route tests to reference the route component via Route.options.component instead of importing the component directly.
