Propose Minimal Grants

Provide the smallest set of GRANT statements that match observed needed_grant values. Prefer role-based grants when the user already uses roles.

Example pattern:

-- Direct grants
GRANT SELECT ON system.processes TO user_x;
GRANT SELECT ON INFORMATION_SCHEMA.COLUMNS TO svc_y;
GRANT CLUSTER ON *.* TO svc_z;

-- Role-based grants (preferred)
GRANT SELECT ON system.processes TO role_analytics;
GRANT role_analytics TO user_x;
