Add prioritized transport, bounded reconnect, and configurable keepalive

Carry numeric priorities through encrypted RPC and adapter writers with bounded admission. Correct push semantics and socket lifecycle cleanup, expose dispatch gating, and add opt-in connection health.

Preserve the WebSocket setup API while allowing applications to override keepalive settings. Enable Android socket publication and document the 0.7.2-SNAPSHOT release workflow.
