/**
 * compat.ts —— 版本敏感代码的**唯一窄腰**（INDEX §C：版本差异代码只许出现在
 * 窄腰文件，能力探测优先，禁止读宿主版本号）。
 *
 * 本插件已核实的两处分叉（findings §1.1 #5 / 迁移执行期补勘）：
 * 1. 持久化设置面：0.1.7+ 走 `configForms.get(ns)`；≤0.1.5 走
 *    `settingsScope.bind({ namespace })`。0.1.7-rc.1 的 client-ui-settings 包
 *    已不含 `settingsScope` 字样（2026-10-04 node_modules 全文核查）——两服务
 *    按代互斥，双 scoped-inject 天然不会双触发。
 * 2. 草稿回填：≤0.1.5 在 `input.for(actx).actions.setDraft`，0.1.7+ 直挂
 *    `.setDraft`（compat/0.1.5:src/client/index.ts vs 本分支同文件）。
 *
 * 缺席服务上的 scoped-inject fiber 永久 PENDING：与 `dsh-family.tab` 在持有者
 * （跨插件族，非宿主本体）缺席时的惰性等待同型，不阻塞插件其余半区——
 * 插件级 inject 清单因此**只含六线通用服务**，防整插件 PENDING 静默失活。
 *
 * All @deepseek-ai/* imports are type-only (client bundle purity).
