ci: upload HTML review report as artifact

[lklimek]

Summary

• Instruct grumpy-review to render HTML instead of markdown (interactive report with Chart.js charts, severity filtering, sorting)
• Save report.json + report.html to a known directory ($REPORT_DIR)
• Add upload-artifact step so the report is downloadable from the Actions run (14-day retention)
• Add Bash(cp *) to allowed tools for file operations

Test plan

• Trigger a review on a test PR with the claudius-review label
• Verify grumpy-review produces report.html (not just report.md)
• Verify the artifact claude-review-report-pr-<N> appears in the Actions run
• Download the artifact ZIP, extract, and open report.html — confirm charts and filtering work
• Verify artifact is skipped gracefully if no report was produced (e.g. timeout)

No manual test scenario file needed — this is a CI-only change.

Poem

🐰 I hopped through CI, nose all a-gleam,

Saved reports in HTML, a rabbit's dream,
report.json snug, artifacts stacked high,
Retained for two weeks beneath GitHub sky,
I celebrate with a twitch and a sigh.

In @.github/workflows/claude-code-review.yml:
- Line 29: The workflow sets REPORT_DIR but never ensures it exists, so create
the directory before Claude runs by adding a step that runs mkdir -p "${{
github.workspace }}/review-report" (i.e., mkdir -p "$REPORT_DIR") and ensure
that this step executes prior to any steps referencing REPORT_DIR (including the
Claude invocation and the artifact collection step that copies/writes files).
Update or add the pre-flight/setup job step so REPORT_DIR is created with
correct permissions and is available for subsequent steps that write files into
it.
