"""owner model grants: default grant set + per-org policy

Revision ID: e6f7a8b9c0d1
Revises: d5e6f7a8b9c0
Create Date: 2026-10-14 09:00:00.000000

Owned by Agent 1 (PLAN-v2 §6). Adds the two owner-side tables of the model-grant
workstream: the default set copied into every new organization, and the
per-organization policy (employee cap, monthly budget, automation/MCP switches).

``org_model_grants`` itself is foundation-owned and already exists.
