/**
 * Tests for workflow.inline_plan_threshold config key and routing logic (#1979).
 *
 * Verifies:
 * 1. The config key is accepted by config-set (VALID_CONFIG_KEYS contains it)
 * 2. The key is documented in planning-config.md
 * 3. The execute-plan.md routing instruction uses the correct grep pattern
 *    (matches <task at any indentation, since PLAN.md templates differ)
 * 4. The workflow guards threshold=0 to disable inline routing
