deslop(claude): role-router 简化 + regex 去重 + stderr 错误日志

按 critic + 3 reviewer agent 反馈:
- HIGH: bare catch {} 改 catch(e){console.error(...)} 暴露 bug
- MED: regex 去重复 (develop|develops? → develops?, fix|fixes → fixes?, requirement|requirements? → requirements?)
- MED: 4 处 {continue:true,suppressOutput:true} 抽 NOOP 常量
- MED: test JSON.stringify(.sort()) → 不可变的 sortKey helper
- skip: createHookOutput 抽 lib (违反"不改 OMC keyword-detector" 决策)
- skip: ROLES enum (3 值 over-engineering)

post-deslop 回归: 10/10 PASS
