Port project packaging to pyproject.toml

[ilouzl]

Summary

Migrate packaging from legacy setup.py to a modern pyproject.toml-based configuration (PEP 621 / setuptools).

Motivation

• Standardize build metadata for tools like pip, build, and CI
• Remove legacy manual publish patterns and simplify maintenance
• Align with current Python packaging best practices

Scope

• Add pyproject.toml with [build-system], [project], and setuptools config
• Move package metadata, dependencies (including platform-specific bleak pins), and dev extras from setup.py
• Keep version in tapsdk/__version__.py (dynamic version attr) unless we decide to consolidate
• Decide how to handle long description (Readme.md + History.md concatenation today)
• Remove or reduce setup.py to a thin shim if still needed
• Verify python -m build produces equivalent sdist/wheel
• Confirm automated PyPI publish workflow still works after migration

Out of scope

• Changing runtime SDK code
• Changing release/tag process

Acceptance criteria

• pyproject.toml is the source of truth for package metadata
• pip install -e .[dev] works on Linux, macOS, and Windows
• CI passes
• Tag-triggered PyPI publish workflow succeeds
