Custom Routes 0.3.0

Added local AI model import.

• Import both approved EfficientSAM-Ti ONNX files with Android's system file
  picker instead of downloading them in the app.
• Model files are verified by size and SHA-256 before use.
• Download remains the primary setup option, and manual marking continues to
  work without the model.

Custom Routes 0.2.0

Improved editor controls.

• Reworked editor action buttons and refreshed role colors.
• Removed the AI Exclude tool: the bundled segmentation model cannot
  represent excluded areas, so exclude taps never took effect. Refine masks
  with AI Include, paint, and erase instead.
• Moved hold deletion into the editor action row.
• Clearer editor tips and consistent data-control dialog wording.

Custom Routes 0.1.0

Initial release.

• Mark climbing holds manually or with optional on-device AI assistance.
• Assign route roles and refine hold outlines.
• Save local projects and export full-resolution JPEGs.
