Font family IDs were duplicated across 5 files (types.ts, setup.ts,
index.ts, SKILL.md, preferences.example.json) with inconsistent
mappings — Comic Shanns was 4 in some places but actually 8 in
Excalidraw source. This caused wrong fonts to render on canvas.
Fix: create src/font-families.json as the canonical font data, import
it in types.ts, and derive all other references from it. Static docs
now point to the JSON file instead of duplicating the mapping.

Add a preference system that lets users configure default font, roughness,
fontSize, and strokeWidth — with three scopes (session/folder/global).
Skill layer (Step 1 in SKILL.md):
- Reads .claude/excalidraw-preferences.json (folder) then
~/.claude/skills/excalidraw-skill/preferences.json (global)
- If neither exists, prompts user interactively on first use
- Session-only scope keeps preferences in-memory without saving
Server layer (index.ts):
- loadPreferences() reads the same files at startup
- Replaces hardcoded fontFamily ?? 1 with USER_PREFS.fontFamily
- Folder-level preferences override global; user values override both
Also ships preferences.example.json as a template (preferences.json
is gitignored).
