实验室：按用户开关的实验功能基座#117
Conversation
Labs is a card on the settings page: features still being tried out,
off by default, switch stored server-side per user.
- sr_user_lab_feature (user_id, feature, enabled, created_at, updated_at);
no row means off. Migration adds the table and its two indexes.
- LabRepo: listByUser / isEnabled / upsert on the Postgres client.
- LabService: registry is an overridable method (empty here so a
self-hosted build sees no change); status active reads the switch,
graduated is on for everyone, retired is off for everyone.
assertUrlAllowed() throws LAB_FEATURE_DISABLED when a URL needs a
feature the user has not turned on; gatedFeatureForUrl() is the hook a
hosted backend overrides to say which URLs are gated.
- LAB_FEATURE_DISABLED (400) carries the feature's display name in the
localized message (zh / en / es), so clients show it as-is.
- GET /v1/user/labs returns { features: [{ key, status, enabled, enabled_at }] }.
- POST /v1/user/setting/enable|disable with key "lab:<feature>" flips
the switch; UserService takes LabService.
- Regenerated router and DI.

实验室是设置页的一张卡片：实验功能按用户开关，默认关，开关存服务端。这个 PR 是开源基座，注册表为空，自托管看不到任何变化；托管后端用同名子类注册具体功能。
sr_user_lab_feature（user_id, feature, enabled, created_at, updated_at），一人一功能一行，没有行就是关。迁移建表和两个索引。LabRepo：listByUser / isEnabled / upsert。LabService：注册表是可覆盖的方法。三种状态：active读用户开关，graduated对所有人开，retired对所有人关。assertUrlAllowed()在保存前拦截需要实验功能的链接，gatedFeatureForUrl()是托管端覆盖的钩子，这里返回 null。LAB_FEATURE_DISABLED（400），三语文案带功能名，客户端可以原样显示。GET /v1/user/labs返回{ features: [{ key, status, enabled, enabled_at }] }；POST /v1/user/setting/enable|disable的 key 以lab:开头时写开关。UserService多一个LabService参数。验证：vitest 6 个文件 29 条通过（新增 13 条）；tsc 没有新增错误。
基于 #116（导出）的分支，那个合并后这个会自动改成对 main。
