  • fix MCP ValidationError on blank stdin lines and bump to 0.4.5

    Some MCP clients send blank lines between JSON messages. The stdio
    transport tried to parse every line as JSONRPCMessage, crashing with
    a Pydantic ValidationError. _filter_blank_stdin() installs an OS-level
    pipe that relays stdin while silently dropping blank-only lines.

    Closes #201
