/**
 * Shared task mutation-intent classifier.
 *
 * Single authority for reading a task's wording, answering two different
 * questions from one prohibition analysis:
 *
 * - `classifyTaskMutationIntent` / `expectsImplementationMutation`: does the
 *   task REQUIRE file changes? Consumed by the completion mutation guard,
 *   which blocks completion, so its vocabulary is deliberately narrow.
 * - `taskMayMutate`: COULD the task plausibly change files? Consumed by
 *   acceptance level inference, which only raises evidence gates, so its
 *   vocabulary is deliberately broad (any bare write verb).
 *
 * Explicit read-only wording ("do not modify", "review only") is a task-level
 * intent only when no write imperative survives outside those phrases. A task
 * like "Do not modify tests; implement the fix" is an implementation task with
 * a scoped constraint, not a read-only task.
