26.9:品牌统一(fileshare)+ 版本号改为日期式
- 数据库默认文件 filecodebox.db → fileshare.db(config.go 默认值与全部文档/编排同步)
- Go module filecodebox → fileshare(全部 import 同步,build/vet/test 全绿)
- 应用版本 APP_VERSION 2.5.6 → 26.9(health 接口已验证返回 26.9)
- deploy 编排统一:compose 项目名、Postgres 默认凭据、minio 桶名、env 注释
- JWT issuer、存储临时目录前缀、web 包名同步 fileshare
- CI:镜像 tag 以 APP_VERSION 为唯一版本源,main/tag 推送即发布
  ${VER} + latest;tag 触发时校验 tag 名与 APP_VERSION 一致,防错版
- 本地开发库文件已改名 fileshare.db(含 -shm/-wal 清理)
