Address Copilot review feedback on PR

- Fix call-chain example consistency in CLAUDE.md and agent-orchestration.md
  (chain lists already-invoked agents, "step N" matches chain length + 1)
- Renumber architect.md Task Checklist (was skipping 3) and replace
  "Leave messages" step with dispatcher-driven "Suggested next agent"
- Replace "Leave a message to the Sorter" with signal via Suggested next agent
- Clarify "Do NOT write to other agents' files" → only prompt/config files
  (.claude/agents/*.md), normal vault edits still allowed
- Fix agent count 10→8 in docs/getting-started.md
- Initialize SKILL_COUNT before conditional block in launchme.sh
