Find an existing stem session\n\nThe directory plugin works with stem sessions already created in the Mozonic\napp. For local stem files or a ZIP, direct the user to upload and create the\nsession at https://app.mozonic.com first. Then find it with\n`mozonic_list_stem_sessions` and inspect it with\n`mozonic_get_stem_session(session_id=...)`.\n\n## 2. Render\n\nWhen analysis is done:\n`mozonic_render_stem_session(session_id=..., output_mode=...)`\n\n- `output_mode=\"mix\"` — balanced stereo bounce\n- `output_mode=\"mastered_mix\"` — bounce + mastering; add `target_profile`\n  (streaming_default, loud_streaming, club_loud, podcast, commercial_loud)\n\nAlso async — poll, then fetch artifacts with\n`mozonic_download_stem_session(session_id=...)`.\n"
