- Added `SvgShape` variant to `VectorShape` in `hcie-protocol`, allowing for SVG rendering of complex shapes.
- Updated serialization to skip old shape variants for backward compatibility.
- Implemented SVG generation functions in `svg_templates.rs` for various shapes (arrow, star, rhombus, etc.).
- Created `svg_render.rs` to parse SVG strings and tessellate paths using `usvg`.
- Modified rendering logic in `hcie-vector` to handle `SvgShape` and integrate with existing shape rendering.
- Updated shape creation API in `hcie-engine-api` to support SVG shapes.
- Enhanced property editing and shape synchronization in both `hcie-egui-app` and `hcie-iced-app` to accommodate new SVG shapes.
- Added comprehensive documentation for new features and changes.
- Improved code readability by formatting function parameters and conditionals.
- Updated tooltip implementations to use a consistent style across various components.
- Added vector angle property to tool settings and integrated it into the vector shape rendering logic.
- Enhanced the rendering of shapes such as Cross, Bolt, and Arrow4 to improve visual fidelity.
- Refactored dock and sidebar components for better organization and clarity.
- Fixed various minor issues and improved logging for better debugging.
