test_streamable_http.py isn't covered by test coverage

Initial Checks

• I confirm that I'm using the latest version of MCP Python SDK
• I confirm that I searched for my issue in https://github.com/modelcontextprotocol/python-sdk/issues before opening this issue

Description

We have a lot of pragma: no cover in this test file:

python-sdk/tests/shared/test_streamable_http.py

Line 123 in f54b18a

class ServerTest(Server): # pragma: no cover

Especially on the server itself, run_app, etc etc. indicating we're not correctly capturing the test coverage here.

Discussed with @maxisbey and this is likely due to Multiprocessing so we need to restructure tests here to not use MP

Example Code

Python & MCP Python SDK

Hi, I'd like to work on this!

Proposed approach (split into small PRs):

PR 1: Refactor basic_server, event_server, and json_server fixtures from multiprocessing.Process + uvicorn to in-process httpx.ASGITransport, following the pattern already used in test_1363_race_condition_streamable_http.py and test_streamable_http_manager.py. This removes ~12 pragma: no cover markers.

PR 2: Refactor the context_aware_server fixture similarly, removing the remaining ~4 markers.

This keeps each PR small and review-friendly. Let me know if this direction makes sense!
