docs(design): HM team-control design referencing Claude Code enterprise paradigm
Synthesizes Claude's admin-setup/authentication/server-managed-settings/settings/
managed-mcp/auto-mode docs into a team-management design for HM, mapped onto the
analogy (client≈Claude Code, HM≈Claude.ai admin console, AM≈cloud agent) and
grounded in HM's existing primitives (new-api users/groups/sk-token model-limits/
quota, plus our V2 device auth, resource bindings, agent templates, /v1 gateway).
Covers org/team/seat model, roles, allocation, managed-settings push over the V2
channel, managed agent/tool catalog, auth/SSO, auto-mode, audit, and a phased plan.
