/**
 * Firecrawl Diagnostics Capability (firecrawl tech-plan §3, D8).
 *
 * Probes Firecrawl connectivity with a single, cheapest-possible request
 * — one basic /v2/scrape of a small stub URL — so the doctor command can
 * verify a credential authenticates without burning many credits.
 *
 * The probe intentionally avoids /team/credit-usage (rate-limit safety,
 * mirroring the Tavily doctor which probes with /search rather than the
 * throttled /usage endpoint). A basic scrape costs one credit and is
 * bounded by the scrape rate limit.
 *
 * Boundary rules (ARCHITECTURE.md §2):
 *   - May import the diagnostics contract, Adapter-local config,
 *     Adapter-local scrape transport, and normalized errors.
 *   - Must NOT import command presentation or another Provider's Adapter.

/**
 * Build the Firecrawl DiagnosticsCapability. The probe performs ONE
 * /v2/scrape of a small stub URL (`formats:["markdown"]`, `proxy:"basic"`)
 * so it costs a single credit — the cheapest credible authentication
 * probe. Shared execution owns the retry policy; this transport performs
 * exactly one attempt per invocation.
 *
 * When `diagOptions.probe` is false, `invoke` resolves immediately without
 * touching the network — the doctor command skips probing unconfigured or
 * tools-disabled Providers before reaching this Capability.
