feat: add get_members tool, refactor get_circles via _famlistfamily helper (v0.4.7)

famlistfamily response already contains members[] on each circle object.
get_members(circle_id=None) extracts id, name, email, role, right, color,
avatar, circle_id and circle_name. get_circles refactored to use the new
_famlistfamily() helper, eliminating duplicated auth/call/logout logic.
SPEC.md updated with full famlistfamily response structure.
