Custom column-major DataFrame table renderer using imgui_bundle draw lists.

Key design constraints:
- All expensive work (stats, widths, col-to-array) is done ONCE at table creation.
- Per-frame work is O(visible_cells) only.
- Column settings and metadata are polars DataFrames.
- Settings UI shows one column at a time (search to select).
- Filtering uses polars/numpy expressions, not Python list comprehensions.
- Data generation uses numpy for bulk random data.

This is a bubblewrap script I use to isolate claude-code from my personal computer

Environment:
- CODE_SESSION_STORAGE: Required storage location for session home folders
- CODE_CONFIG_BASENAME: The vscode ~/.config location name. Defaults to "Code - OSS". Depends on linux distribution
- CODE_EXTENSIONS_PATH: e.g. a file you can provide like `code --list-extensions > ~/.config/vscode-extensions.txt`
                        that will be loaded in the container's vscode
