/**
 * Firecrawl Quota Capability (firecrawl tech-plan D8, critique C4).
 *
 * Maps the Firecrawl /v2/team/credit-usage response into one normalized
 * `QuotaCategory` with `unit:"credits"` and `name:"Credits"`. The
 * normalizer is pure; the capability factory owns configuration
 * resolution, the single direct transport attempt, and failure
 * normalization. Shared execution owns retry policy.
 *
 * Credit-usage shape: the live endpoint surfaces "remaining credits"
 * (investigation §1.2). The exact field names are a non-gating verify
 * item (tech-plan §7 #4), so the normalizer extracts `remaining` + `used`
 * defensively across common variants and derives `limit = used +
 * remaining`. Field names are tuned during live verification (FC-06).
 *
 * Boundary rules (ARCHITECTURE.md §2):
 *   - May import the quota contract, Adapter-local config, Adapter-local
 *     quota client, and normalized errors.
 *   - Must NOT import command presentation or another Provider's Adapter.
