Add --extra dev flag to uv sync in CI workflow

[Copilot]

CI workflow fails when attempting to run ruff because optional dev dependencies aren't installed. The pyproject.toml defines ruff, pytest, and related tools under [project.optional-dependencies].dev, but the workflow runs uv sync without the --extra dev flag.

Changes

• Updated .github/workflows/ci.yml line 26: uv sync → uv sync --extra dev

This ensures dev tools (ruff, pytest, pytest-cov, pytest-asyncio) are available for linting and testing steps.

Original prompt

Problem

The CI workflow is failing with the error:

error: Failed to spawn: `ruff`
  Caused by: No such file or directory (os error 2)

This is happening because ruff is not being installed during the workflow run.

Root Cause

The workflow file .github/workflows/ci.yml runs uv sync without installing optional dependencies. However, ruff is defined as an optional dev dependency in pyproject.toml under [project.optional-dependencies].

Solution

Update the "Install dependencies" step in .github/workflows/ci.yml to install dev dependencies by changing:

- name: Install dependencies
  run: uv sync

to:

- name: Install dependencies
  run: uv sync --extra dev

This will ensure that ruff and other dev dependencies (like pytest, pytest-cov, pytest-asyncio) are installed before the linting and testing steps run.
