fix: add missing issues:write permission for PR autolabeler (#20)

The reusable workflow (commit-check/.github/.github/workflows/pr-labeler.yml)
requires 'issues: write' permission because the release-drafter autolabeler
uses the Issues API to set labels on PRs.

When a caller invokes a reusable workflow with 'permissions: {}' at the top
level and only 'pull-requests: write' + 'contents: read' at the job level,
'issues' defaults to 'none'. The reusable workflow cannot escalate its
permissions beyond what the caller grants, causing a startup_failure.

This adds 'issues: write' to the caller job-level permissions so the
reusable workflow's GITHUB_TOKEN can create PR labels.
