fix(ai-review): revert to single-job review with enhanced prompt

Multi-job parallel pipeline proved too fragile for CI:
- Agent tool unavailable in claude-code-action
- 6-job workflow: artifact passing failures, turn budget exhaustion
- GLM API errors cascade across jobs

Reverts to proven single-job architecture. Keeps enhanced prompt
combining security, quality, and CCS compliance scopes.

+            ${{ steps.review-prompt.outputs.content }}
 
-            Read the file `review_inputs.md` for the raw outputs from all 3 reviewers (security, quality, CCS compliance).

-            ## IMPORTANT: Writing the Final Review
-            After merging and assessing, use the `Write` tool to write the final unified review to `${{ env.REVIEW_OUTPUT_FILE }}`.
-            Use `Write` tool directly — do NOT use `Edit`.
-            Do NOT post GitHub comments yourself. The workflow will publish the saved file.
-            Do NOT modify any source code files.
-            IMPORTANT: Do NOT use shell operators (|| &&) or heredoc (<<) in bash commands.
+            ## IMPORTANT: Writing the Review
+            After completing your analysis, use the `Write` tool to write the final review markdown to `${{ env.REVIEW_OUTPUT_FILE }}`.
+            Do NOT use `Edit` tool — use `Write` tool directly to create the file in one shot.
+            Do NOT post any GitHub comments yourself. The workflow will publish the saved file.
+            Do NOT modify any source code files — this is a READ-ONLY review.
 
             End your review with:
-            > Parallel review by `${{ env.REVIEW_MODEL }}` (3 focused reviewers + orchestrator merge)
+            > 🤖 Reviewed by `${{ env.REVIEW_MODEL }}`
+
+            IMPORTANT RULES:
+            - Use `Write` tool to overwrite `${{ env.REVIEW_OUTPUT_FILE }}` with the complete review
+            - Do NOT use shell operators like || or && in bash commands
+            - Do NOT use heredoc (<<) syntax in bash commands
+            - Use simple, single-purpose bash commands only
