chore: Modernize Development Toolchain: Poetry → UV + Ruff Migration

[HideBa]

This PR modernizes the development toolchain by migrating from Poetry to UV and consolidating linting
tools with Ruff.

📦 Package Management Migration

• Poetry → UV: Migrated from Poetry to UV for faster dependency resolution and installation
• pyproject.toml: Converted to standard PEP 621 format with hatchling build backend
• Dependencies: Updated all dependencies to latest versions
• Python support: Updated from >=3.9 to >=3.10 (required for latest Click)

🔧 Development Tools Overhaul

• Ruff: Replaced flake8, black, and isort with a single, fast linter/formatter (~10-100x faster)
• Typos: Replaced mypy with typos spell checker (more appropriate for this codebase)
• Configuration: All tools configured in pyproject.toml with sensible defaults

🛠️ New Makefile Commands

make lint # Ruff linting
make typos # Spell checking
make format # Code formatting
make format-check # Check formatting without changes
make fix # Auto-fix linting issues
make check # Run all checks (lint, typos, test, format-check)

🔍 Issues Fixed

During migration, fixed several typos discovered by the new spell checker:

• tranform_polygon → transform_polygon
• indicies → indices
• classifed → classified

🏗️ CI/CD Updates

• GitHub Actions: Updated workflows to use UV and new toolchain
• Repository: Fixed references from HideBa/ahn_cli to tudelft3d/ahn_cli
• Python matrix: Updated to test Python 3.10, 3.11, 3.12

📚 Documentation Updates

• README.md: Added UV installation option
• CLAUDE.md: Updated with new commands and toolchain information

✅ Verification

• All 11 tests pass ✅
• Linting with Ruff passes ✅
• Spell checking passes ✅
• Code formatting verified ✅
• No regressions detected ✅

This migration brings the project up to modern Python development standards while maintaining full
backward compatibility and test coverage
