docs: document repo-name completion and the server: output prefix

- README: completion note now covers repo-name completion for
  desc/delete/add-remote, not just --section; new Notes entry on the
  server: prefix for helper/sync passthrough.
- SKILL.md: gotcha explaining that server:-prefixed lines are remote
  echo (not errors) and that repo list output is not prefixed.

Docs only. (The global ~/.claude copy of the skill got the same gotcha,
outside the repo.)

 - Every operation is idempotent and safe to re-run.
