Updates

This update introduces new geometry tools, measurement features, and major improvements to the MeshLib Viewer, PDF export, and cross-platform builds.

🆕 Mesh Thickening (makeThickMesh) with smoother non-voxel-based offsets and automatic direction smoothing.
🆕 Filling Surface (MR::FillingSurface) generates lattice structures using porous and cellular filling methods.
🆕 Swept Volume (MRSweptVolume) creates a mesh by sweeping geometry along a line, simulating a CNC toolpath.
🆕 Cut by Projection (cutMeshByProjection) projects a contour onto a mesh and slices it along the projected path.
Mesh Decimation now preserves texture coordinates and color maps, and removes small disconnected components.
Subdivision: maintain region option to keep selected regions unchanged.

🆕 Rotation pivot: new public API, static pivot option, and touchpad gesture support.
🆕 Dashed 3D lines with customizable patterns.
🆕 Point Measurement Object type with rendering support.
🆕 Per-axis measurements with improved rendering and integration in the info panel.
🆕 Viewport masks can now be saved to user settings.
Global Basis redesign with visibility masks and a global 3D grid.
Viewport controls: new per-viewport buttons and toggles, stabilized floating buttons.
Line antialiasing enabled globally with per-item overrides.
Theme updates: grid color control, palette save/restore, improved discrete color picking.
UI improvements: monospaced labels for measurements, global UI scaling, improved tooltips and selection handling.
Smarter “Last Used Directory” handling and scene-saving defaults.
Plugins notified on schema load, with faster plugin and ribbon initialization.
WebAssembly: better hotkey handling, error recovery, and path resolution.
MRU file names shortened for OS compatibility.
