/**
 * `brain` setup wizard section (E-CONFIG-AUTH-UNIFY E3 / T9425).
 *
 * Controls how BRAIN context is surfaced inside AGENTS.md by toggling
 * `brain.memoryBridge.mode` across three operator-visible values:
 *
 *   - `'digest'`   — AGENTS.md gets a `cleo memory digest --brief` directive
 *                    (no `.cleo/memory-bridge.md` written). Wire value stays
 *                    `'cli'` so existing project configs continue to resolve
 *                    correctly; the wizard label was renamed to "digest" to
 *                    match the user-facing CLI command.
 *   - `'file'`     — Legacy behaviour: write `.cleo/memory-bridge.md` and
 *                    `.cleo/nexus-bridge.md` so they get `@`-injected.
 *   - `'disabled'` — Suppress BRAIN-driven AGENTS.md augmentation entirely.
 *
 * V2 additions (T9610):
 *   - `isConfigured()` — returns `true` when `brain.memoryBridge.mode` is set (BRAIN-6).
 *   - Retention days prompt (BRAIN-3).
 *   - Embedding toggle prompt (BRAIN-4).
 *   - Displays current bridge mode, embedding state, and retention days (BRAIN-1).
 *   - Section description printed before prompts (GEN-6).
 *
 * Non-interactive contract:
 *   - `options.nonInteractive === true` + `options.brainBridgeMode` →
 *     persist that value; no prompts.
 *   - Missing `--brain-bridge-mode` under `--non-interactive` →
 *     section short-circuits with error.
