* chore(docs): add video demo to README.md for enhanced project visibility
* refactor(ai): centralize Claude Agent SDK env resolution with debug logging and model retry
Extract shared buildClaudeAgentEnv() and getClaudeAgentDebugFilePath() into
resolve-claude-agent-env.ts to eliminate duplicated env setup across all
server endpoints. Add model fallback retry logic (retry without explicit
model on exit code 1) and diagnostic hints from debug log tail on failures.
* fix(canvas): normalize layout justify/align values from CSS aliases
AI-generated nodes may use CSS-style values like "flex-start",
"space-between", "middle" etc. Add normalizeJustifyContent and
normalizeAlignItems to map these to internal enum values in both
the layout engine and the property panel.
* fix(canvas): improve text and path rendering accuracy
- Remove icon-specific bounding box override on path scaling to prevent
pathOffset drift that visually offsets icons in logo containers
- Only use Textbox for explicit fixed-width text modes instead of any
node with width > 0, preventing unwanted word wrapping on auto-width text
- Add widthSafetyFactor for Latin text estimation (1.14x vs 1.06x CJK)
to reduce accidental line wraps from font width variation
* feat(ai): add input icon affordance rules and trailing icon alignment
Prompt AI to include semantic icons in form inputs (search, password,
email). Add normalizeInputTrailingIconAlignment post-pass in
role-resolver to auto-set justifyContent="space_between" on input
frames with a trailing icon node.
* feat(ai): persist model selection across sessions via localStorage
Add preferredModel and selectModel to ai-store with localStorage
read/write. Hydrate on mount to restore user's last chosen model.
Add isHydrated flag to agent-settings-store to prevent race
conditions during provider list construction.

- Introduced a layout engine for auto-layout computation, including padding resolution and fit-content size calculations.
- Added a node creator for various drawing tools (rectangle, frame, ellipse, line, text) to streamline object creation.
- Implemented object modification handling to sync changes back to the document store, improving interaction with Fabric.js.
- Enhanced text measurement utilities for better width and height estimation, including support for CJK characters.
- Added new API endpoints for AI icon retrieval and validation, supporting multimodal content analysis.
