feat: migrate Python dependency management from Poetry to uv

[devsy-bot]

Summary

This PR migrates the Python dependency management system from Poetry to uv across the entire Skyvern repository, including the main project and integration packages.

Key Changes

• Project Configuration: Updated pyproject.toml to use PEP 621 standard format with hatchling build backend
• CI/CD Workflows: Replaced Poetry GitHub Actions with uv for faster dependency resolution and installation
• Docker: Updated multi-stage build to use uv export instead of poetry export
• Integration Packages: Converted langchain and llama_index integration packages to use uv configuration
• Development Scripts: Updated run_skyvern.sh and other scripts to use uv commands
• Documentation: Added comprehensive migration guide and updated existing docs

Benefits

• Performance: Significantly faster dependency resolution and installation
• Standards Compliance: Better adherence to Python packaging standards (PEP 621, PEP 517)
• Simplicity: Reduced toolchain complexity with fewer moving parts
• CI Efficiency: More efficient dependency caching in CI/CD pipelines

Migration Impact

• Removes ~23k lines from poetry.lock files
• All existing functionality preserved with improved performance
• Comprehensive migration documentation provided for developers

Test Plan

• Updated all pyproject.toml files to use uv/hatchling format
• Updated CI/CD workflows to use uv actions
• Updated Docker configuration for uv export
• Updated development scripts and documentation
• Added migration guide with troubleshooting instructions
• CI workflows should pass with new uv configuration
• Docker builds should work with uv export
• Local development setup should work with uv commands

Changes that Break Backward Compatibility

This migration introduces breaking changes for developers currently using Poetry:

• Local Development: Developers must install uv and use new commands (uv pip install -e .[dev] instead of poetry install)
• Build Process: Package building now uses uv build instead of poetry build
• Virtual Environment: Virtual environment activation changes from poetry shell to source .venv/bin/activate
• Dependency Management: Adding/removing dependencies requires uv add/remove instead of poetry add/remove

Documentation

Comprehensive documentation updates included:

• Migration Guide: Added MIGRATION_FROM_POETRY.md with detailed migration instructions, command mappings, troubleshooting steps, and rollback procedures
• README Updates: Updated skyvern/webeye/README.md to reference uv instead of Poetry for installation instructions
• Developer Onboarding: Updated development setup instructions to use uv commands

Pin the uv version instead of using 'latest' to ensure reproducible Docker builds.
