/**
 * R87 penalty 清理 + L1d 业务前缀扩展 复合补丁 (2026-04-25)
 *
 * 两项修复：
 *
 * 1. R87 penalty 去除 self-auditor (与 R86 boost 语义冲突)
 *    - 原因: R87 触发 "bookworm 在哪/是什么/如何配置" 时 penalty self-auditor,
 *            但 "bookworm 自检在哪配置/自检怎么用" 这类查询依然应锚定 self-auditor,
 *            penalty 导致 R86 boost 被抵消为负 → 误路由到 developer-expert 下游
 *    - 保留 project-audit-expert / reviewer-expert penalty (重型审计仍需降权)
 *
 * 2. R84 negative-lookbehind 扩展 uniapp/taro/svelte/solid/qwik
 *    - 原因: 当前仅排除 vue/next/react/angular/nuxt 业务前缀,
 *            "uniapp 路由消歧/taro 钩子管线/svelte 路由引擎" 等短语会被 R84 误吸锚定到 self-auditor
 *    - 新增前缀: uniapp / uni-app / taro / svelte / solid / qwik
 *    - 同步覆盖 R86 相同模式 (系统自检 lookbehind 不变, 仅 R84 扩展)
 *
 * 幂等: 两项修复各自 sentinel 检测；已应用则跳过。
 * 原子: tmp + rename。
 * 备份: .bak.r87-l1d.<ISO>
