The welcome DM used to be handed to the running service over the CLI
admin socket, which stamped `cli:local` as the sender. On a strict
messaging group (any fresh DM wired by init-first-agent), that tripped
the unknown-sender approval gate — the operator's own bootstrap script
ended up requesting its own approval. Fix by writing the welcome
directly into the session's inbound.db with a `System` sender; the
running service's host-sweep wakes the container on its next pass.
Also drop `--no-cli-bonus`. Now that init-cli-agent always wires
cli/local to the scratch CLI agent, every caller of init-first-agent
had to pass --no-cli-bonus to avoid double-wiring; the flag has become
mandatory, so it's just removed. The cli-bonus branch goes with it.
Skill docs updated in lockstep.
