# Run all tests
#
# The Go and Rust clients are not covered: on main both abort when no .env file
# is present, so they cannot be driven without credentials. Making them start
# credential-free is a change in their own directories, so their coverage lands
# with those changes rather than here.
#
# Nor is the Ruby weather server: the mcp gem does not stamp the resultType
# field that 2026-07-28 requires, so the test client rejects its responses.
