#1 Missing PR checkout for workflow_dispatch trigger

.github/workflows/gito-code-review.yml L15-L16

When triggered via workflow_dispatch, the actions/checkout step checks out the default branch (or selected branch) rather than the Pull Request specified by the pr_number input. This causes the code review tool to analyze the wrong codebase while posting comments to the specified PR, resulting in incorrect review results. The checkout ref must be explicitly set to refs/pull//head for workflow_dispatch events.

Affected code:

15:       - uses: actions/checkout@v6
16:         with: { fetch-depth: 0 }

Proposed change:

      - uses: actions/checkout@v6
        with:
          fetch-depth: 0
          ref: ${{ github.event_name == 'workflow_dispatch' && format('refs/pull/{0}/head', github.event.inputs.pr_number) || github.ref }}

Looked into the suggested change, and it appears to be incorrect. From the actions/checkout@v6 docs:

The branch, tag or SHA to checkout. When checking out the repository that triggered a workflow, this defaults to the reference or SHA for that event. Otherwise, uses the default branch.

So it will checkout the PR by default. Web search AI says that it will actually checkout the merge commit as if the PR were to be merged into master, which is even better.
