/**
 * Deterministic quick-lane classifier (issue #3984).
 *
 * The deep-interview and ralplan skills describe a task-routing surface in
 * prose: small, clearly scoped, low-risk work should take a quick lane
 * (minimal orchestration) while vague, ambiguous, risky, or wide-breadth work
 * keeps the existing deep path. That gate existed only as prompt guidance, so
 * it was not auditable or testable. This module encodes the same signals as
 * deterministic, pure code so eligibility and exclusions are explicit and
 * regression-covered.
 *
 * The classifier is intentionally conservative and fail-closed:
 * - Any exclusion signal forces the `deep` lane, even when the task also names
 *   concrete files or symbols. Safety is never overridden by a concrete anchor.
 * - The `deep` lane preserves the existing deep/interview behavior untouched;
 *   this module only *classifies*, it never routes or mutates.
 * - A task with neither a concrete anchor nor an exclusion defaults to `deep`
 *   because boundness cannot be confirmed.

 * 2. Otherwise, any concrete anchor yields `quick`.
 * 3. Otherwise, `deep` (boundness could not be confirmed).
