Fix missing id and if on Setup uv step in code-complexity and code-duplication lock files

[Copilot]

The gh-aw compiler v0.87.4 emitted the "Setup uv" step without id: setup-uv or the if: hashFiles('pyproject.toml', 'uv.lock') != '' guard when generating lock files that use uvx via the Serena MCP (gh-aw-code-complexity-detector, gh-aw-code-duplication-detector). Because this repo contains pyproject.toml and uv.lock, the "Expose uv in workspace" step ran with UV_PATH="" and failed:

ln: failed to create symbolic link '/opt/hostedtoolcache/gh-aw-tools/current/x64/bin/uv' -> '': No such file or directory

Without an explicit id: on the step, ${{ steps.setup-uv.outputs.uv-path }} always resolves to an empty string regardless of whether setup-uv ran successfully.

Changes

• gh-aw-code-complexity-detector.lock.yml — Add id: setup-uv and if: hashFiles('pyproject.toml', 'uv.lock') != '' to the "Setup uv" step, matching the correct pattern in all other compiled lock files.
• gh-aw-code-duplication-detector.lock.yml — Same fix.

Before (broken — emitted by compiler v0.87.4 for workflows using uvx):

- name: Setup uv
  # zizmor: ignore[github_action_from_unverified_creator_used]
  uses: astral-sh/setup-uv@20cfd1bf945f4377ade1205e4dbc17946fc9a30d # v10.0.1

After (matches the correct pattern in all other lock files):

- id: setup-uv
  if: hashFiles('pyproject.toml', 'uv.lock') != ''
  name: Setup uv
  # zizmor: ignore[github_action_from_unverified_creator_used]
  uses: astral-sh/setup-uv@20cfd1bf945f4377ade1205e4dbc17946fc9a30d # v10.0.1
