Replace all 'Inter' string literals with DEFAULT_FONT_FAMILY from
constants. Add loadFontsForNodes() that collects font families from
text nodes and loads them into CanvasKit, called after clipboard
paste and .fig file import.
Replace 8 inline { r: 0, g: 0, b: 0, a: 1 } literals across core
with shared constants from constants.ts. Also reuse CANVAS_BG_COLOR
in fig-export.ts instead of duplicating the value.
