 * Resolve the rule-set directories a command should operate on.
 *
 * - If `args` is non-empty, each entry is resolved to an absolute path relative to `cwd`
 *   and MUST contain a `ruleset.yaml` — an explicitly-named directory that isn't a rule
 *   set is a hard error (the caller made a mistake, not the glob).
 * - Otherwise, the nearest `.bffless/config.json` (found by walking up from `cwd`) is
 *   loaded and its `ruleSets` glob patterns are expanded, resolved *relative to the
 *   config file's own directory* (the project root that owns `.bffless/`), not `cwd`.
 *   Glob matches that don't contain a `ruleset.yaml` are silently filtered out — globs
 *   are inherently permissive over directory structure (e.g. a `skills` dir sitting
 *   next to rule sets), so filtering rather than erroring here is the useful behavior.
 * - No args and no config (or a config with no/empty `ruleSets`) is a helpful error, not
 *   an empty array — silently validating nothing is never what the caller wants.
