SUI 0.3.0

This release adds application and editor surfaces, improves text quality and
retained rendering, and expands the source-built language bindings.

Highlights

• Added retained docking workspaces, editor cursor grabbing and raw mouse motion,
  safe initial desktop window placement, and GPU interoperability contracts.
• Expanded Python and JavaScript bindings for the newer Rust widget and editor
  surfaces. These bindings remain source-built and are not registry publications.
• Reused paragraph shaping and glyph measurements across layout widths, added
  size-only text measurement, and reduced repeated Flex layout probes.
• Retained widget output, scene fragments, renderer packets, GPU batches, and
  shared scene command storage to reduce repeated frame preparation work.
• Overlapped GPU preparation with CPU startup and added reproducible widget,
  frame, shrinkwrap-conversation, and editorial-flow benchmarks.
• Improved font hinting, transformed text rasterization, LCD coverage and atlas
  sampling; isolated node-edge animation repaint work and analytic grid dots.
• Added provider-neutral image icons, bounded browser tabs, compact dialogs,
  and reserved scrollbar gutters.
• Updated dependencies and bundled Lucide icons to 1.47.0.
• Made the Shrinkwrap and Editorial text demos follow shared theme colors,
  typography, and radii, including theme changes while paused and cached text
  layouts at unchanged window sizes.
• Added a size-focused web release profile and kept the demo within the existing
  12 MiB uncompressed Wasm budget without removing features.
• Restored Rust 1.90 compatibility, corrected offscreen demo-picker test
  interactions, and resolved strict workspace Clippy findings.
• Bundled complete Noto Sans Arabic and Hebrew fallback fonts for offline web
  and Android text, and corrected caret hit testing across right-to-left runs.
• Restored corrupted Unicode, emoji, and IME sample text in the demo and its
  text-editing benchmarks.
• Continued VSync presentation and animation/timer delivery inside native
  window move/resize loops, including while the title bar is held still.
• Preferred compatible Direct3D12 hardware on Windows to improve native window
  drag pacing, retaining explicit backend selection and automatic fallback.
• Kept focused, visible VSync windows presenting cached content so an idle UI
  does not lower a variable-refresh monitor's refresh rate.
• Reused GPU vertex buffers, upload staging storage, and output-transform
  resources to avoid repeated allocations and interaction-time frame stalls.
• Fixed inflated frame-time/FPS readings after idle mouse motion by attributing
  input costs and latency only to a pending redraw across native and test hosts.
• Made the demo FPS counter measure host frame cadence, including VSync and
  idle intervals, while reporting render work separately.
• Retained action cards independently so hover, press, and focus transitions
  repaint only the affected cards instead of rebuilding an entire picker grid.
• Centralized builder/runtime resource registration so rejected duplicate handles
  preserve the original resource, and shared native/web GPU resource setup.
• Shared button press, text-change, and caret lifecycle logic across controls;
  organized composites, binding infrastructure, and renderer internals by feature.
• Made binding signatures language-neutral with explicit numeric and identifier
  types, and changed export verification to follow Rust modules and declarations.
• Fixed selector observer write-back deadlocks and removed obsolete reactive
  dependencies after completed widget phases while preserving cached phases.
• Bounded text-layout and renderer path caches, preserving layouts and geometry
  still owned by live widgets or frames, and avoided full reindexing on collection
  appends.
• Matched node-graph spatial bounds to configured Bézier curvature so visible
  curves remain available for hit testing and culling.
• Added the optional sinomo-ui-webview crate for WRY-backed native child
  webviews with retained layout, lifecycle synchronization, thread-safe
  controls, typed page/title/IPC events, and application-owned browser policy.
• Prevented synchronous live-test flushes from advancing future animation
  frames based only on render wall time, avoiding timeouts in repeating demos.
• Added affine transformed widget subtrees and Canvas-hosted normal widgets.
  Canvas now uniformly scales paint, input, semantics, text, images, and nested
  layout by default, with screen-space/custom zoom policies and touch pinch;
  retained node widgets use the same path.
• Added the sinomo-ui-nodes graph-editor library with typed nodes, edges,
  handles, controlled and uncontrolled observable state, retained custom node
  widgets, dynamic measurement, incremental spatial indexing, subflows,
  resizing, edge reconnection, per-element semantics, lifecycle events,
  animated viewport and edge behavior, controls, minimap, and graph-owned
  appearance overrides.
• Added a comprehensive sui-demo node-editor workspace behind the
  default-enabled nodes feature, covering controlled and uncontrolled graphs,
  retained node controls, every edge family, subflows, editing, indexing,
  semantics, and viewport telemetry.

Compatibility and release notes

• Update SUI crate dependencies together from 0.2 to 0.3. Lucide keeps its
  independent 1.47.0 version and now depends on the 0.3 SUI family.
• Event::RawMouseMotion and WindowEvent::Moved require handling in exhaustive
  event matches. Public widget appearance/configuration structs gained fields,
  including ControlPalette::selection_border; update explicit struct literals.
• Rust 1.90 remains the minimum supported version.
• Linux webview builds require the system WebKitGTK 4.1 development libraries;
  the Rust bindings do not install the browser engine.
• Browser support remains alpha and Android remains experimental. Native
  webviews are an optional crate; Python wheels and Node addons are not part of
  this Rust registry release.
