/**
 * peaks skill search — CLI primitive for S0 of the 4.0.0-beta.5
 * peaks-solo dispatcher release.
 *
 *
 * Wired into the existing `peaks skill` group by
 * `src/cli/commands/core/skill-command.ts` (one import + one call).
 * The command ALWAYS emits a JSON array on stdout, even on the
 * no-match case (which exits 0 with `[]` per plan §"Match rules (v1)").
 *
 * Exit codes (locked in plan §"API Contract"):
 *   0 — success (may be empty array)
 *   1 — invalid args (Zod validation failure)
 *   2 — unexpected error (skill pool read fail, etc.)
