`POST /commands/run`, stamped `command.run` the way `world.call`,
`dt.start` and `gc.place` are (PROTOCOL.md §20.11). The plugin keeps the
key, fills {steamid} and {name} and decides who is online; the sidecar
moves the line and knows nothing of what a command does (D384, no
allowlist). Joins protocol 14, still unreleased on edge.
Stamp test: the body's key, commands and recipients pass through byte for
byte, placeholders and quotes included.
