The frontend sends agent_name and is_bootstrap via the context field
in run requests, but services.py only forwards a hardcoded whitelist
of keys (_CONTEXT_CONFIGURABLE_KEYS) into the agent's configurable
dict. Since agent_name was missing, custom agents never received
their name — make_lead_agent always fell back to the default lead
agent, skipping SOUL.md, per-agent config and skill filtering.
Similarly, is_bootstrap was dropped, so the bootstrap creation flow
could never activate the setup_agent tool path.
Add both keys to the whitelist so they reach make_lead_agent.
Fixes#2222
