"""End-to-end client tests against the in-process mock LSP server.
Spins up :file:`_mock_lsp_server.py` as an actual subprocess, drives
it through real LSP traffic, and asserts diagnostic flow. This is
the closest thing we have to integration coverage without requiring
pyright/gopls/etc. to be installed in CI.
