Research 018 graduates: ADRs 0173–0177 and to-be 37, the operator's machine

Every configurable thing on a node is a module, the home included, and a
module is whatever it declares (0173, extending 0040). A node varies a module
only through a setting rendered into the file or a kept region, never an edit
(0174, extending 0011; issue 168 first). One tool runtime per node serves every
module's tools on the host side, never in a container; the console is its
serving mode, renamed node-tools (0175, extending 0150; 0047/0150/0152 carry
dated notes). The login shell is a node seat held by one shell module with
`execute` as its contract (0176). A unit may be user-scoped and the service
manager is a node seat held by systemd (0177).

To-be 37 is handed off in-progress to mesh-host, mesh-controller, mesh-tools
and mesh-catalog, with the build in order: the account on every node, the
runtime, zsh, systemd, then the graphical stack. To-be 29 keeps ~/.ssh and
points at 37; 33 §6 and 34 are amended; the glossary gains node tools, bundle,
kept region, installed/holding, and retires flavor.

    0040 already says this and only its examples are narrow.
