Fix workflow setup for uv sync --dev in both template and repository

[Copilot]

The workflows were failing due to incorrect uv sync --dev configuration. Both the template's GitHub Actions workflow and the repository's own workflow needed updates to properly support uv-based dependency management.

Changes

Template workflow ({{cookiecutter.project_slug}}/.github/workflows/test.yml):

• Dependency installation: Replaced uv pip install -e ".[dev]" with uv sync --dev
• Cleanup: Removed Verify uv installation step

Repository workflow (.github/workflows/tests.yml):

• No environment variables needed - uv manages its own virtual environment

Repository configuration (pyproject.toml):

• UV configuration: Added [tool.uv] section with managed = true for proper uv project management

# Template workflow changes
-      - name: Install dependencies
-        run: |
-          uv pip install -e ".[dev]"
-          uv pip list
+      - name: Sync dependencies
+        run: uv sync --dev

# Repository pyproject.toml changes
+[tool.uv]
+managed = true

Root Cause

The initial attempt added UV_SYSTEM_PYTHON: "1" which prevented uv from properly installing packages into its virtual environment. The CI logs showed packages being resolved but not installed ("Audited in 0.00ms"), causing the "pytest not found" error. Removing this environment variable allows uv to create and fully populate its own virtual environment.

The uv sync command is uv's native project management approach that syncs from lockfile. It requires the ability to create and manage its own virtual environment without interference from system Python settings.

@copilot - still failing. Presumably more general edits to workflow setup needed.

Fixed in b88e749. The issue required updates to both the template workflow and the repository's own workflow:

1. Repository workflow: Added UV_SYSTEM_PYTHON="1" environment variable
2. Repository pyproject.toml: Added [tool.uv] managed = true for proper uv project management

Both workflows now properly configured for uv sync --dev.

Run uv sync --dev

Fixed in 96fb263. The issue was UV_SYSTEM_PYTHON=1 preventing uv from properly installing packages into the virtual environment.

The CI log showed "Audited in 0.00ms" which meant no packages were installed. Removed UV_SYSTEM_PYTHON from both workflows to allow uv to create and populate a proper venv where pytest can be found.
