feat(orchestrator): hierarchy view from council offices with a separate agent order

The Agents views gain a Hierarchie view: an org chart of the chair and
the line offices read from the council claims. The operator appoints,
hands over and recalls an office there; the page signs each change with
the passkey and a host unit (client/offices.py, offices path unit)
verifies the signature, removes a live holder itself and runs a plain
council.py claim for the successor. council.py loses the --operator
flag, so no agent can override a live holder.

The agent order is now separate from task priority: rasci.py agents
order stores it in agent-order.json beside the register through the
nofollow helpers and never writes a --prio pin. It only breaks ties of
equal task rank, also among the queue grants. The Hierarchie view edits
it as a drag list.

Host units run the installed skill scripts, so orchestrator.sh keeps the
offices unit off while the installed council.py, nofollow.py or rasci.py
differ from the tree. Job files, council files and hub records are read
with O_NOFOLLOW and O_NONBLOCK and size caps; nofollow.rewrite replaces
a claim without creating directories, so a beat never revives a released
office.
