Implement static image export with dimension control: **Python Backend**: - Create `squiggy/export.py` with PNG/SVG export functions - Add `export_plot_to_png()` and `export_plot_to_svg()` for direct export - Add `export_current_plot()` wrapper for extension integration - Store last generated plot in global `_last_plot_figure` variable - Update all plotting functions to call `set_current_plot()` **TypeScript Extension**: - Add `squiggy.exportPlot` command with export dialog UI - Prompt for format (PNG/SVG/HTML), dimensions, and DPI - Call Python export functions via PositronRuntime - Update `SquigglePlotPanel` with `exportPlotWithPython()` method **Features**: - PNG export with configurable width, height, and DPI - SVG export with configurable width and height - HTML export (existing functionality, now integrated) - Interactive dialog for dimension control - Selenium auto-managed via Selenium Manager (>=4.6) **Dependencies**: - Uses existing `export` optional dependency group in pyproject.toml - Requires `pip install squiggy-positron[export]` for PNG export - SVG export has no additional dependencies **User Experience**: - Command palette: "Squiggy: Export Current Plot (PNG/SVG/HTML)" - Prompts for format selection - Prompts for dimensions (width, height) - Prompts for DPI (PNG only) - Shows save dialog with appropriate file extension - Displays success message with file path Closes #132
- Remove unused `io` import from squiggy/export.py - Remove unused `svg_io` variable assignment - Sort imports in squiggy/__init__.py - Remove unused ExportOptions interface from plot-commands.ts - Prefix unused parameters with _ in squiggy-plot-panel.ts All tests pass and linting is clean.
