Bounded client for an explicitly provisioned local Intelligence session.
This module neither admits policy nor discovers, installs or trusts a peer.
Callers own fresh scoped keys, sequence allocation, revocation and fallback.
Directory of the daemon’s endpoint files (daemon.pid, daemon.sock, the
start lock and stderr log): the data directory, so LEAN_CTX_DATA_DIR, the
XDG layout and a legacy ~/.lean-ctx install each get their own daemon.
The Windows pipe name is derived from it for the same reason.
Where releases up to 3.12.0 kept the endpoint files: the OS data-local
directory, whatever the data directory was. Read only to stop a daemon that
such a release started.
