clean up comments

- Create new updateClaudeComment function in operations/comments
- Add comprehensive unit tests following image-downloader pattern
- Update MCP server to use extracted function
- Refactor update-comment-link.ts and update-with-branch.ts to eliminate duplication
- All tests passing (10 new tests for update-claude-comment)

 ## Advanced Configuration
 
-### Custom Environment Variables
-
-You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    claude_env: |
-      NODE_ENV: test
-      CI: true
-      DATABASE_URL: postgres://test:test@localhost:5432/test_db
-    # ... other inputs
-```
-
-The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.

 ### Custom Tools
