Align the stdio shutdown sequence with the MCP spec: close the server’s input, wait for exit, send SIGTERM if needed, and SIGKILL as a last resort.
Motivation and Context
The MCP spec recommends a careful shutdown sequence for stdio transport to avoid leaving orphaned or stuck server processes. This change follows those steps, making shutdowns more reliable and predictable.
How Has This Been Tested?
All tests pass (except one unrelated skipped test).
