Pull request overview
Adds rectangle-select zoom to the Beads dependency graph webview by introducing a selection overlay and switching zoom anchoring to be based on a persisted pan+zoom transform.
Changes:
- Introduces
graphPanstate and applies zoom viatranslate + scaleCSS transforms. - Adds pointer-driven rectangle selection to zoom into a selected region, plus double-click “fit to viewport”.
- Updates webview HTML/CSS and metadata tests to include the selection overlay and new transform behavior.
