/**
 * `mantle validate` — Loop 1 of the SDK authoring contract
 * (ADR-0007). Walks YAML manifests + handler source, emits
 * structured Diagnostic JSON or pretty text. Exit code 0 on success
 * (no errors; warnings allowed), 1 on any error.
 *
 * Default paths (relative to cwd):
 *   manifests root: ./manifests
 *   handler source: ./src
 *
 * Override with --manifests <dir> / --source <dir>.
 *
 * Output mode:
 *   --format json   → JSON array on stdout (default when piped)
 *   --format text   → pretty-print on stdout (default when TTY)
 *
 * Phase:
 *   --phase preview  → grammar checks only; deploy-only gates skipped (default)
 *   --phase deploy   → production/deploy checks
 *
 * Per the clean-architecture rules this is a thin adapter: it loads
 * files, constructs the request DTO, calls the use case, formats the
 * response. No business logic.
