log_collector_worker connects the bus at startup, builds a thread-safe
system.log publisher, and hands it to each container-stream thread
through _stream_container's new publish_fn parameter. Publishing fires
right after the JSON record is written — same rate-limiter path, no
extra parsing, compact payload (decky/service/event_type/attacker_ip/
timestamp) so subscribers can redraw without re-reading the DB.
Bus stays optional: if get_bus() fails or DECNET_BUS_ENABLED=false the
factory returns a no-op publisher and the stream thread calls it
unconditionally. Hook failures are logged and never abort the thread.
