/**
 * `doctor --read-only` and `doctor --offline` (issue #335): a health check a
 * caller can run without it changing anything or touching the network.
 * doc/agent-exec-protocol.md §10.
 *
 * Read-only is the default under `--json` (mono-agent's checks never change
 * anything) unless `--fix`/`--install` asks for writes. It is about files, not
 * the network: the version check still asks the npm registry, through a
 * throwaway npm cache. `--offline` skips every check that needs the network.
