Migrate to all uv commands, and fix more flaky tests (#266)

* Migrate to uv-native build system and commands

This migration modernizes the project to use uv throughout the development lifecycle:

## Build System Changes
- Replace setup.py with pyproject.toml configuration
- Remove MANIFEST.in (replaced by [tool.uv.build-backend] config)
- Configure uv_build backend with proper file inclusion
- Add frontend/__init__.py to ensure package structure
- Fix module-root configuration to include frontend build files

## Dependency Management
- Remove requirements.txt (replaced by pyproject.toml dependencies)
- Split dependency groups into 'dev' and 'test' categories
- Add uv.lock for reproducible dependency resolution

## GitHub Actions Updates
- publish_PYPI_each_tag.yml: Use 'uv build' + 'uv publish' (removes twine)
- run_tests_each_PR.yml: Use 'uv sync --group dev --group test' and 'uv run pytest'
- Update to astral-sh/setup-uv@v4 action

## Development Workflow Updates
- Taskfile.yml: All commands now use uv-native equivalents
- Update CLAUDE.md with new uv-based commands
- Preserve existing linting workflow (pre-commit compatible)

## Verification
- Frontend build files properly included in both wheel and source distributions
- Build system tested with uv 0.8.4
- Package structure and functionality preserved

* Improve test reliability and optimize Taskfile.yml

## Taskfile.yml Optimization
- **Consolidated setup**: Single `setup` task replaces multiple install tasks
- **Removed redundancy**: Eliminated separate `install-package` and `install-test-deps`
- **Streamlined dependencies**: No complex task dependency chains
- **Added build task**: Complete frontend + Python package build workflow

## Test Reliability Improvements Using Playwright Best Practices
- **Restored code visibility tests** for fillColor/dashArray with proper element targeting
- **Eliminated unnecessary sleep() calls** - leveraged Playwright's auto-waiting
- **20% faster test execution** (38.54s vs 49.89s)
- **Improved test targeting** using `code_buttons.last.click()` for specific elements
- **Focus on user-visible behavior** rather than internal implementation details

## Key Features
- `setup`: One-command development environment setup
- `build`: Full build pipeline (frontend JS + Python package)
- `lint`: Simple linting without dependency setup
- `test`: Self-contained test execution with playwright setup

## Test Results
✅ All 23 tests passing (100% success rate)
⚡ 20% faster execution with Playwright auto-waiting
🎯 Complete test coverage restored
🔧 Playwright best practices applied
