Description

Migrate the repo from pip/build-based workflows to uv:

• CI/build/test workflows now use astral-sh/setup-uv + uv build / uv pip install / uvx
• Dev tooling deps are defined in pyproject.toml dependency groups; requirements.txt and requirements-dev.txt are removed
• uv.lock is committed; docs CI uses uv sync --frozen --group dev for reproducible builds
• scripts/generate-* no longer install Python deps (generation is Rust-side; build happens via uv build)
• Closes Update scripts to use uv bitcoindevkit/bdk-python#26
• Supersedes chore: Prefer uv over pip for dependencies bitcoindevkit/bdk-python#29

Notes to the reviewers

• We intentionally keep PyPI publishing via pypa/gh-action-pypi-publish@release/v1 to avoid changing release semantics beyond the pip→uv migration.
• We intentionally don’t pass --outdir dist: uv build outputs to dist/ by default.
• Publishing remains via pypa/gh-action-pypi-publish@release/v1 to avoid changing:
  • artifact download layout expectations,
  • GitHub environment/permissions semantics,
  • and publish behavior beyond the pip→uv migration.

Tests run locally:

• uv sync --frozen --group dev
• uv run python -m unittest discover --start-directory ./tests --pattern "test_offline_*.py" --verbose
• uv build --wheel -v
