* pin pydantic-monty to 0.0.8
* rename tool/prompt/resource base modules to avoid decorator name shadow

* preserve original module paths in deprecation warnings
* clarify when sys.modules shims can be removed
* fix: forward custom_route endpoints from mounted servers
When a child server with custom HTTP routes (registered via
@server.custom_route()) is mounted onto a parent, the routes were
silently dropped because _get_additional_http_routes() only returned
self._additional_http_routes without recursing into mounted providers.
This caused 404s for endpoints like /readyz health checks that worked
in v2 but broke in v3 (regression).
The fix updates _get_additional_http_routes() to traverse providers,
unwrap _WrappedProvider layers (from namespace transforms), find
FastMCPProvider instances, and recursively collect their server's
custom routes.
Fixes#3457
* fix: narrow type annotation from BaseRoute to Route
All items in _additional_http_routes are Route objects (created via
Route(...) in custom_route()). Using list[Route] instead of
list[BaseRoute] fixes the ty type checker failure where .path is
accessed on BaseRoute which doesn't have that attribute.
Removes unused BaseRoute imports from both server.py and transport.py.
* fix: revert route type to list[BaseRoute] to fix ty errors
The previous commit narrowed _additional_http_routes from list[BaseRoute]
to list[Route], which broke:
- component_manager appending Mount objects (Mount is BaseRoute, not Route)
- tests assigning list[BaseRoute] variables (generics are invariant)
Revert to list[BaseRoute] and use isinstance(r, Route) guards in tests
for type-safe .path access.
* fix: remove unused import and fix import grouping
- Remove unused `Route` import from server.py
- Fix import grouping in test_advanced.py (ruff check)
* Address review: move imports to module root, type Provider, add collision note
* fix: sort imports in transport.py
