The stdio channel is the bundle's bus: subscribe asks the runtime (mesh/subscribe), which binds the
module's durable consumer and hands each event over as mesh/event — answered once every matching
handler has taken it, as an error when one failed so the runtime does not acknowledge it; request
asks the runtime (mesh/ask). The session starts as the stdio module loads when the runtime launched
the process, because a handler module subscribes at import, before the launcher says what it
serves; initialize and tools/list are answered once it has. topicMatches as the runtime's. 0.1.6.
