/**
 * `scai doctor` — local-config + credentials diagnostics.
 *
 * Different from `scai cli health`, which probes the live deploy /
 * sites tenant: doctor stays local. It walks the operator's
 * sitecoreai.cli.json + keychain + Node setup and tells them what
 * needs fixing before any remote call should be expected to work.
 *
 * Categories of checks (in order):
 *
 *  1. Runtime — Node version meets the package.json engines floor.
 *  2. Config — sitecoreai.cli.json exists, parses, validates against
 *     the JSON Schema, has a default env (or exactly one env).
 *  3. Per-env — required fields present, deploy token in keychain,
 *     token freshness within TTL.
 *  4. Brand — for each `brand[orgId]` config block, the secret is in
 *     keychain so brand operations have something to mint with.
 *
 * Each check produces a row in the result table. Failures are
 * actionable: every `fail` carries a `hint` naming the exact command
 * or env var that fixes it.
 *
 * Output: human-readable table (default) or `{ checks, summary }`
 * envelope when `--json`. Process exit is non-zero on any `fail`;
 * `--strict` also fails on `warn`.
