replace Oishii example with time orchestrator built by agent teams

Agent teams now bootstrap a self-contained time orchestration workflow
inside agent-teams/.claude/ (command, agent, skill). The prompt, diagram,
and How to Use section all reference the new time-orchestrator pattern
with cd agent-teams && claude → /time-orchestrator.
