V0.0.2 (#10)

* 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.

* chore(package): update version to 0.0.2 and add new build scripts for mac architectures
