* rechunk script

* consolidate isoview arrays - expose public api

* add background imgs and orig xml's

* consolidate corrected/fused

* Add GPU selector and persisted Options popup

- mbo view --list-gpus / --gpu N CLI flags (cli.py)
- ~/.mbo/settings/preferences.json "options" block with gpu_index and
  debug_logging keys, plus get/set helpers (preferences.py)
- "Options" button + popup in the launch dialog with GPU adapter dropdown
  and Debug logging checkbox, both persisted on change (file_dialog.py)
- Persisted choices applied at every launch in _run_gui_impl, including
  direct-path launches that skip the dialog (run_gui.py)

* Wrap dialog tooltips and overflow text to fit dialog width

- Add wrapped_tooltip() helper using begin_tooltip + push_text_wrap_pos
  so long tooltips wrap to ~24em instead of running off the right edge.
- Add text_wrapped_colored() for inline status / hint lines.
- Replace every imgui.set_tooltip() in FileDialog with wrapped_tooltip().
- Wrap the cupy `uv pip install ...` hint onto its own line with a
  proper Copy button (was running off the dialog on `same_line`).
- Wrap dependency / Rastermap status lines so they don't overflow when
  GPU/CPU labels stack up.
