/**
 * Lazy accessor for chatter's flow engine.
 *
 * `@diegoaltoworks/chatter` is an *optional* peer dependency: a top-level
 * value import of `@diegoaltoworks/chatter/flows` anywhere in the module graph
 * makes `import "@diegoaltoworks/talker"` throw for a host that installed only
 * hono, which breaks both the standalone quick start and voice-only usage.
 * Loading the engine at first use instead keeps import time clean and turns a
 * missing peer into an actionable error on the code path that needs it.
 * (Repeat loads are cheap - the ESM registry caches the module.)
 *
 * The same reasoning applies to `openai` (see src/standalone.ts) and
 * `@libsql/client` (see src/db/client.ts); src/peer-deps.test.ts enforces it
 * across the whole source tree.
