Multi-OS routing: hosts advertise capability tags, tasks declare
required_capabilities, Colibri's scheduler (pick_agent/capability_match_score,
already implemented) places each task on a qualifying host. Documents the
vocabulary, the probe->capability mapping, the SkillManifest.required_capabilities
addition, central-daemon topology, and the tmux-screenshot skill as the worked
example (why dropping FreeBSD Pillow loses no capability).
