fix(connect): disable context takeover in websocket transport

The `threshold` option in `perMessageDeflate` is ignored due to context
takeover being enabled. This leads to WebSocket RPC messages being
unconditionally compressed.

Most RPC channel messages are small, and unconditionally performing
message compression has measurable performance impact.

Disable context takeover (for both server and client) to let compression
threshold option to take effect.
