fix(python): budget cold profile initialization

The Windows x64 installed-wheel job timed out while waiting for initialize even though the same head passed on rerun. Exact packaged-runtime VM evidence showed a 6.47-second first cold handshake and 2.69-2.94-second warm fresh-home handshakes, leaving too little variance below the public 10-second default.\n\nRaise the independent initialize default to 30 seconds in both Python SDK configuration layers. Ordinary turn and shutdown timeouts remain unchanged, callers retain an explicit override, and tests plus paired documentation pin the public behavior.
