Fix ain-js ESM/CJS interop and lesson tag deduplication

- ain-client.ts: use `.default ?? module` pattern for ain-js import
  to handle Node ESM wrapping CJS default exports as { default: Ain }
- record-lesson.js: resolve ain-js from cogito/node_modules using
  require.resolve paths, and deduplicate lesson_learned tag
