feat(routes): FastAPI prefixes, ASP.NET endpoint groups, wrapped server actions on the Screens tab

- python.ts postExtract: APIRouter(prefix=) and literal include_router(prefix=) composed down the include tree (module import, alias, local); a computed prefix leaves that mount alone; full-stack-fastapi-template 23 routes named by path
- csharp.ts: handler-first MapPost(Handler[, "path"]) under the endpoint-group class, the app's $"/api/{groupName}" head read in postExtract, RoutePrefix honoured; detection covers Endpoints/ files; CleanArchitecture 10 routes
- tier-synthesizer: a type argument between a client call and its parentheses (useSWR<T>(…), ky.get<T>(…)); recorded callee without it
- screens.ts: a file-scope navigation attributed to the value spanning it; a value nothing calls attributed to the functions mentioning it in importing files (request-time source read, bounded); steps.ts lends navigates edges to a value root
- tests: servers fixture (FastAPI prefixed routers, ASP.NET endpoint group end to end), frameworks.test.ts (group form, RoutePrefix), cross-tier (generic useSWR)
- docs: CHANGELOG, plan, playbook rows
