ci(*:skip): Migrate CI to uv

Merge after #6679

Pull request overview

This PR migrates the Flower framework project's CI and local developer workflows from Poetry to uv. uv was already being used by the devtool project, and this change completes the migration by updating all GitHub Actions workflows, shell scripts, and documentation to use uv sync, uv run, uv build, and uv publish instead of Poetry commands. The bootstrap action is also simplified by removing the poetry-skip and uv-skip optional flags, making uv always available.

Changes:

• Updated .github/actions/bootstrap/action.yml to always install uv (removing Poetry and related skip flags)
• Updated all .github/workflows/*.yml CI jobs to use uv sync --frozen and uv run --no-sync instead of python -m poetry install and direct script calls
• Updated framework/pyproject.toml to add [tool.uv] and [tool.uv.sources] configuration, and [tool.coverage.run] data_file config
• Updated framework/dev/*.sh scripts to use uv build and uv publish
• Updated documentation (framework/docs/source/*.rst, dev/README.md, framework/uv.md) to reflect the uv-based workflow

The --token argument in uv publish --token ${{ secrets.PYPI_TOKEN_RELEASE_FLWR }} is not quoted. In GitHub Actions, ${{ secrets.PYPI_TOKEN_RELEASE_FLWR }} is inlined directly into the shell command, so the token value should be quoted to prevent word splitting and other shell issues. The token should be passed as --token "${{ secrets.PYPI_TOKEN_RELEASE_FLWR }}" or, better yet, provided via an environment variable that is then referenced as a quoted shell variable.

Suggested change

	uv publish --token ${{ secrets.PYPI_TOKEN_RELEASE_FLWR }}
	uv publish --token "${{ secrets.PYPI_TOKEN_RELEASE_FLWR }}"

Step 3 instructs contributors to "Install uv" but provides no specific installation command or reference. The previous version had an explicit pip install poetry==2.3.2 command. While the prerequisites section links to the uv docs, it would be clearer to include the recommended installation command here (e.g., curl -LsSf https://astral.sh/uv/install.sh | sh) or at least a link to the uv installation page.
