/**
 * Named rule PRESETS a `.vigilesrc.json` can `extends` — the ESLint
 * `recommended` model, stored as data on the rule GROUPS.
 *
 * 🔴 WHY A PRESET READ AT LOAD TIME, NOT RULE LINES WRITTEN AT SETUP TIME. Every
 * rule keeps its own built-in default; a group gates only because its preset
 * turns it up. `init` used to do that by WRITING nine `"<rule>": "error"` lines
 * into the new repo's config — a snapshot of the group on the day `init` ran. A
 * repo adopted before a rule joined the group never got it from an upgrade, and
 * re-running `init` to fetch it rewrote far more than the rule (#338). An
 * `extends` preset is resolved by the loader on every run, so the repo follows
 * the group as the installed vigiles ships it, and an explicit `rules` entry
 * still overrides it.
 *
 * WHERE THE PRESETS COME FROM — not from here. A preset is a field of a group
 * (`RuleGroupSpec.preset`: its name and the severity it sets), and a rule's
 * membership is its own `group` field; both live in the outer rule layer
 * (`src/rules/`) and arrive as parameters. So this file names no rule and no
 * group, and moving a rule between groups is an edit to that rule alone.
 *
 * ⚠️ RAISING A RULE UNDER A PRESET THAT SETS `error` IS A BREAKING CHANGE (a `!`
 * commit, a semver major): it can turn a consumer's CI red with no edit on their
 * side. A preset that sets `warn` can grow freely. ESLint treats
 * `eslint:recommended` the same way.
