"""
inline 插件 [workers.config] 对齐（网关侧兜底）单测 —— WorkerManager.align_inline_config。

网关侧在创建 inline 副本之前，按「配置优先来源模式」（根 config.toml 的
[cache].launch_worker_count）对齐插件配置：cache 模式取共享缓存里的段，
toml 模式以 config/workers/<type>/config.toml 为准并覆盖缓存。目的是让网关与
worker 包版本解耦——worker 包仍是旧版时，旧版 on_init 只拿到 toml 展平配置，
会出现“前端显示缓存值、实际跑 toml”。

用 dict 作缓存桩，验证两种模式下插件拿到的配置与缓存/文件两侧的取值一致。
