M07: Opts snapshot introduction

- Add modules/opts_snapshot.py with create_opts_snapshot(opts)
- Capture snapshot in process_images_inner after prepare_prompt_seed_state
- Full shallow copy of opts.data via SimpleNamespace
- No runtime behavior change; snapshot write-only for M07

Made-with: Cursor
