feat: add agent-orchestrator (ao) as a self-hosting project
- Create claude-ao-session: worktree-based session manager for ao
(Linear tickets, GitHub PRs, AO_SESSION env var)
- Add ao|agent-orchestrator case to all shared scripts:
claude-batch-spawn, claude-spawn, claude-status, claude-open-all,
claude-review-check, claude-bugbot-fix
- Rewrite CLAUDE.orchestrator.md with full self-hosting instructions:
commands reference, workflows, architecture, tips
- Session prefix: ao, metadata: ~/.ao-sessions/, worktrees: ~/.worktrees/ao/
