Session log: multi-user setup, audit + gap fixes, Howard onboarding package

Two session logs:
- session-logs/2026-04-16-session.md: cross-cutting (multi-user, audit, infrastructure)
- guru-rmm session log appended: MSI installer, Len's Auto Brokerage, Uranus, migration drift

Gap fixes: GrepAI initialized + MCP server added, Ollama models pulling,
settings.json created (bypassPermissions), MCP_SERVERS.md written.
