Adds `spike/issue-742-managed-agents-executor/` with:
- `demo.py`: standalone Python script that authenticates to the Managed Agents
beta API, provisions an environment + agent, starts a session, runs two
conversational turns (with cross-turn state recall verification), and prints
cold-start and per-turn latency measurements.
- `README.md`: full integration assessment covering provisioner changes needed,
A2A routing conflict (primary blocker — sessions have no addressable URL),
cost model, API gaps table, and a no-ship recommendation with a 3-week effort
estimate if we proceeded anyway.
Recommendation: no-ship for primary executor. Revisit as a batch/cron worker
in Phase H once Molecule's MCP server is feature-complete.
Closes#745. References #742.
