Migrate from Poetry to UV, update Python dependencies, and modernize stlite to use CDN

[Copilot]

This PR migrates the project from Poetry to UV package manager, updates all Python dependencies to their latest stable versions, and modernizes the stlite integration to use CDN delivery.

Changes Made

Package Manager Migration

• Replaced Poetry with UV: Converted pyproject.toml from Poetry format to standard Python packaging format compatible with UV
• Updated build system: Changed from poetry-core to hatchling with proper source directory configuration
• Removed Poetry lock file: Deleted poetry.lock and generated new uv.lock for dependency resolution

Dependency Updates

All Python dependencies have been updated to their latest stable versions:

• Streamlit: ^1.30.0 → >=1.48.1 (major UI and performance improvements)
• Pandas: ^2.1.2 → >=2.3.2 (enhanced data processing capabilities)
• Scikit-learn: ^1.3.2 → >=1.7.1 (new ML algorithms and performance optimizations)
• PyLDAvis: ^3.4.1 → >=3.4.1 (no change needed, already latest)
• Ruff: ^0.1.4 → >=0.12.9 (significant linting and formatting improvements)

Stlite Modernization

• Updated stlite to CDN delivery: Replaced local asset files with CDN links for better performance and easier maintenance
• CSS: assets/stlite/build/stlite.css → https://cdn.jsdelivr.net/npm/@stlite/[email protected]/build/stlite.css
• JavaScript: assets/stlite/build/stlite.js → https://cdn.jsdelivr.net/npm/@stlite/[email protected]/build/stlite.js
• Version: Updated from 0.51.0 to 0.89.0 (latest stable version)

Documentation Updates

• README.md: Updated installation and usage instructions to use UV commands instead of Poetry
  • poetry install → uv sync
  • poetry run streamlit run src/app.py → uv run streamlit run src/app.py
  • poetry run ruff format → uv run ruff format

Code Quality

• Applied updated Ruff formatting rules to ensure code consistency
• Verified all linting rules pass with the new Ruff version
• Maintained backward compatibility with Python 3.11+

Benefits

• Faster dependency resolution: UV provides significantly faster package installation and resolution
• Latest security patches: All dependencies updated to include recent security fixes
• Improved performance: Updated packages include performance optimizations and CDN delivery for stlite
• Better developer experience: UV's improved error messages and faster operations
• Reduced bundle size: CDN delivery eliminates need for local stlite assets
• Future-ready: Using modern Python packaging standards and web delivery practices

Testing

• ✅ All dependencies import successfully
• ✅ Streamlit application starts and runs correctly
• ✅ Linting and formatting work as expected
• ✅ Fresh environment setup works (uv sync)
• ✅ All README commands verified functional
• ✅ Stlite CDN integration verified

The migration maintains full backward compatibility while modernizing both the development workflow and web delivery approach.
