/**
 * config-client.ts, reading and writing the settings the DAEMON owns.
 *
 * ── The split, and why it is not "all config goes over the wire" ───────────
 *
 * A config key belongs to the runtime that ACTS on it (config-ownership.ts is
 * the authority, and this module never keeps a second copy of its lists). Two
 * scopes matter here:
 *
 * - DAEMON-OWNED (`surfaces.*`, `controlPlane.*`, `watchers.*`, `device.*`,
 *   `automation.*`, `atRest.*`, `payments.*`, `voice.local.*`, …). The daemon
 *   executes these unattended. When a surface hosted the daemon, writing them to
 *   that surface's own settings file happened to work. It does not anymore: a
 *   Telegram bot token saved there would land in the surface's own settings
 *   file, the daemon would never read it, and the save would report success
 *   while configuring nothing. These go over `config.set` and come back over
 *   `config.get` / `settings.snapshot`.
 *
 * - SURFACE-OWNED (rendering, theme, transcript display, keybindings, and the
 *   `daemon.*` / `service.*` switches that say whether THIS installation runs a
 *   daemon at all). These stay local, in the surface's own file, read and
 *   written by the in-process ConfigManager exactly as before. Sending them to
 *   the daemon would make one machine's theme everyone's theme.
 *
 * ── Degrading honestly ─────────────────────────────────────────────────────
 *
 * With no reachable daemon a daemon-owned WRITE fails, loudly, with the
 * refusal reason, it does not fall back to writing the local file. A silent
 * local write is the exact failure this split exists to end: it looks like it
 * worked and changes nothing. A daemon-owned READ falls back to the local
 * value, because a stale-but-real number renders better than a blank field and
 * reads were always allowed to be optimistic.
