v0.1.0

• Add JustificationFont enum exposing the bundled digitalKhatt font with a load() helper that copies the asset to the application support directory and returns its path
• Ship prebuilt native binaries for Android and iOS; drop HarfBuzz/FreeType git submodules so consumers no longer need to build them from source
• Implement kashida justification via the font's LTAT/RTAT variable-font axes instead of glyph-level tatweel insertion
• Tighten kashida solver: bracket the full axis range and return the upper bracket so justified lines reach the target width instead of undershooting
• Use available line width when sizing justified bitmaps and outlines so equal-width lines are no longer clipped
