/**
 * Inline suppression directives, written as SQL comments, that silence findings
 * the author has judged safe. Modelled on `eslint-disable` and tuned to the way
 * migrations read top to bottom.
 *
 * Syntax (in a `--` line comment or a block comment):
 *
 *   -- psm-disable-next-line [rules] [-- reason]   the statement below
 *   -- psm-disable-line      [rules] [-- reason]   the statement on this line
 *   -- psm-disable-file      [rules] [-- reason]   the whole file
 *   -- psm-disable           [rules]               from here…
 *   -- psm-enable            [rules]               …until here
 *
 * `rules` is an optional space/comma-separated list of rule names; omit it to
 * suppress every rule. `reason` (after ` -- ` or `:`) is free text. `psm-ignore`
 * and `psm-ignore-file` are accepted as aliases for the next-line and file forms.
