Summary

Set a distinct integration-test client identity/User-Agent to avoid default mcp/0.1.0 in test traffic.

Changes include:

• Added centralized integration test client identity in integtests/conftest.py:
  • INTEGTEST_CLIENT_INFO = Implementation(name="integtest/mcp", version=<current package version>)
  • INTEGTEST_USER_AGENT = f"{name}/{version}"
• Added autouse test fixtures to enforce defaults:
  • Default client_info for all fastmcp.Client(...) in integration tests.
  • Overridden SessionStateMiddleware outbound User-Agent for server-driven integration flows.
• Updated integration test context setup (mcp_context) to use integration client params and client ID defaults.
• Updated integtests/test_errors.py to use centralized constants for user-agent assertions.
• Bumped project version to 1.44.7 and synced uv.lock.
