/**
 * `xopc providers` — user-friendly hub for managing LLM provider credentials.
 *
 * This command sits on top of the existing auth-profile store (`xopc auth …`),
 * but presents a setup-style surface — `list / set-key / unset-key / schema` —
 * with the same `SetupTask` JSON contract used by other M1 setup commands.
 * Agents (M2 skills) and the WebUI (M3) can consume both shapes uniformly.
 *
 * Capability-provider (image / voice) settings live under `cfg.providers.<id>`
 * and will be wired into this command's flags in a follow-up slice.
