refactor(ci): simplify ai-review to vanilla claude-code-action

- Use anthropics/claude-code-action@v1 directly
- Remove ccs-reviewer wrapper dependency
- Match pr-review-comprehensive.yml pattern
- Keep CLIProxy env vars for model routing
- Restore comprehensive allowedTools for posting

-# Smart concurrency: Prevents self-cancellation when bot posts review comment

-# Problem: When the bot posts a review comment, GitHub fires an issue_comment event.
-# This new workflow run joins the same concurrency group and cancels the in-progress
-# run BEFORE job `if` conditions are evaluated - causing "operation was canceled" error.
-#
-# Solution: Non-actionable triggers (bot comments, comments without /review) get a
-# unique per-run group, while legitimate triggers share the PR-based group for proper
-# cancellation of outdated reviews.

-            Perform a comprehensive code review. Follow the repository's CLAUDE.md for project-specific guidelines.
+            Perform a comprehensive code review with the following focus areas:
 
-            ## Review Focus Areas
+            1. **Code Quality**
+               - Clean code principles and best practices
+               - Proper error handling and edge cases
+               - Code readability and maintainability
 
-            1. 🔒 **Security** - OWASP Top 10, injection, auth bypass, secrets exposure
-            2. ✅ **Correctness** - Logic errors, edge cases, error handling
-            3. 🏗️ **Architecture** - Coupling, cohesion, API contracts, backward compatibility
-            4. 🧪 **Testing** - Coverage, edge cases, test quality
-            5. ⚡ **Performance** - Algorithm complexity, memory leaks, query efficiency
-            6. 📖 **Maintainability** - Naming, complexity, consistency with codebase
+            2. **Security**
+               - Check for potential security vulnerabilities
+               - Validate input sanitization
+               - Review authentication/authorization logic
 
-            ## Output Structure
+            3. **Performance**
+               - Identify potential performance bottlenecks
+               - Review database queries for efficiency
+               - Check for memory leaks or resource issues
 
-            Use visual hierarchy with emojis and `---` separators between major sections:
-            - 📋 **Summary** (2-3 sentences)
-            - ✅ **Strengths** (numbered, with file:line references, use ⭐ for exceptional items)
-            - 🔍 **Observations & Suggestions** (with code examples, priority tags)
-            - 🔒 **Security Considerations** (✅/❌ checklist table)
-            - 📊 **Code Quality Checklist** (✅/❌ table format)
-            - 💡 **Recommendations** (🔴 High / 🟡 Medium / 🟢 Low priority)
-            - 🎯 **Overall Assessment** (✅ APPROVED / ⚠️ APPROVED WITH NOTES / ❌ CHANGES REQUESTED)
+            4. **Testing**
+               - Verify adequate test coverage
+               - Review test quality and edge cases
+               - Check for missing test scenarios
 
-            Be thorough but concise. Skip empty sections. Include code examples for non-trivial suggestions.
-            Use tables for checklists. Bold important terms. Make the review visually scannable.
+            5. **Documentation**
+               - Ensure code is properly documented
+               - Verify README updates for new features
+               - Check API documentation accuracy
 
-            End your review with:
-            > 🤖 Reviewed by `${{ env.REVIEW_MODEL }}`
-
-            ## IMPORTANT: Posting the Review
-            After completing your analysis, post the review as a PR comment.
-
-            STEP 1: First, use the Read tool to check if pr_review.md exists (it may not exist yet, that's OK)
-            STEP 2: Use the Write tool to write your review to pr_review.md in the current working directory
-            STEP 3: Post with: gh pr comment ${{ github.event.pull_request.number || github.event.issue.number || github.event.inputs.pr_number }} --body-file pr_review.md
-
-            IMPORTANT RULES:
-            - Write to pr_review.md (in working directory), NOT /tmp/pr_review.md
-            - 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
+            Provide detailed feedback using inline comments for specific issues.
+            Use top-level comments for general observations or praise.
