appendix-k-loop-dispatch (converted to a skill)

Operational content for /loop dispatch patterns now loads on demand via the s4u-loop-dispatch skill (skills/s4u-loop-dispatch/SKILL.md), installed per project by setup/bootstrap.sh (canon v3, 2026-06-12). This appendix is retired.

The skill now carries the event-dispatch lifecycle, four budget units and anti-patterns 9–10 (waiting agents and purposeless rerun loops), plus skilled-worker selection. Evidence and limits live in §7.10; the catalogue is in §5.3. No watcher or runtime budget gate is installed by this pointer.
