Build a routes.csv file for this application by discovering all navigable routes.

Scan the codebase for route definitions:
- Next.js App Router: app/**/page.tsx directories
- React Router: createBrowserRouter, Route path configs
- Vue Router: routes arrays in router configs
- Angular: RouterModule.forRoot, Routes arrays
- Any URL path patterns in the codebase
- If the app is running, explore navigation in the browser

Output CSV with header: name,path,description,parameters
- name: unique snake_case identifier (e.g. settings_billing, user_detail)
- path: URL path with :paramName for dynamic segments
- description: one-line summary of what the page shows or does
- parameters: semicolon-separated paramName:type pairs; empty for static routes

Example:
name,path,description,parameters
dashboard,/dashboard,Main dashboard overview,
user_detail,/users/:userId,Individual user profile,userId:string
settings_billing,/settings/billing,Billing and subscription management,

Organization: dashboard/home pages first, feature pages next, settings/admin last.
Deduplicate, remove stale entries, validate unique names, paths start with /, params match placeholders.
Write the result to routes.csv in the project root.
