"""Regression tests for version reporting in the top-level `mcp` package
(issue #863).

Covers the same stale-version bug as `test_mcp_server_version.py` for the
standalone `mcp/` server (run via `python -m mcp.server`), which is a
separate implementation from `semantica.mcp_server` and was not covered
by that fix. `semantica.__version__` is the authoritative package
version (see semantica/mcp_server/__init__.py), so all three surfaces
are asserted against it directly.
