QUIC carrier connections now track active logical streams and enforce a
per-connection stream limit, exposing stream opens/closes and limit rejects in
transport telemetry.
The per-connection QUIC stream limit is configurable through
`RAP_VPN_FABRIC_QUIC_MAX_STREAMS_PER_CONN` /
`-vpn-fabric-quic-max-streams-per-conn` and propagated by host-agent install
profiles.
