improve claude workflows clarity and security (#883)
## 📝 Summary - Apply least-privilege permissions — moved permissions from workflow-level to per-job. - Prevent double-trigger on @claude review — claude-response now excludes @claude review comments on the issue_comment path, so only claude-manual-review handles those. - Add concurrency groups — each job cancels stale in-progress runs per PR, preventing redundant parallel executions on rapid pushes. - Add security prompt to interactive mode.
