The shared engine behind the [ringo](https://github.com/davidborzek/ringo)
tools: spawning [baresip](https://github.com/baresip/baresip), the `ctrl_tcp`
wire protocol, the call-event model and a phone command abstraction — free of
any TUI or configuration concerns.
It backs the `ringo` softphone and the `ringo-flow` scenario runner. This is an
internal support crate without a stable public API; pin an exact version if you
depend on it directly.
