With nothing installed, sudo llmgw asks for one machine or three, takes how
to reach the other two (ssh agent, key or password, and a sudo password used
only for the install), checks every machine first, shows the plan and its
command line, and installs. On a control plane it opens a console with the
cluster's state and the next steps. Machines are reached with Go's ssh so a
password works; the store's etcd and access rules use this machine's routed
address rather than a client-facing name.

init --patroni user@host ... installs PostgreSQL, Patroni and etcd on the
given machines over ssh, with this one as the third etcd vote, makes the role
and database, and moves the store in use into the cluster. Each step checks
first, so it changes nothing on a cluster that is up. For a store of several
hosts the control plane publishes each member's role, state and lag from
Patroni, a stopped member as missing, prints it in ctl status, and alerts on
it. Making an administrator on PostgreSQL sent a bool to an integer column;
it sends an integer now.

server init --postgres failed on Rocky with postgresql-setup not found.
The PostgreSQL project's packages (PGDG) provide "postgresql-server",
so dnf can satisfy that name with postgresql16-server — whose unit is
postgresql-16.service, whose tools are in /usr/pgsql-16/bin and whose
setup script is postgresql-16-setup. The code assumed the distribution's
names for all three.
The server unit is now picked from systemd's postgresql* unit files, its
data directory read from the unit's own PGDATA, and initdb run directly
as postgres when that directory is empty, with password logins over TCP.
psql, initdb and the restart use what was found. The unit names and
PGDATA values in the tests are the ones Rocky's and PGDG's packages ship.
Not yet handled: a server initialised with ident for TCP logins, one on a
port other than 5432, and several PGDG versions where the highest is not
the one on 5432.

Installs PostgreSQL with the machine's own package manager when it has
none (initdb with password auth on the RHEL family, whose default is
ident), creates the llmgw role and database with a generated password
kept in /etc/llmgw/secrets/store-dsn, and checks the address connects.
On a machine already on SQLite it stops the gateway, copies the store
so accounts and keys survive, points auth.store at the new address and
starts it again. A move that fails starts the gateway on SQLite again.
server.yaml is edited as text so its comments survive, and kept beside
it. A PostgreSQL init did not install is not resized: it may serve
something else. It refuses to move one PostgreSQL store into another.
