refactor: 迁移至 bashly CLI 与功能域模块结构

- CLI 定义迁移至 src/bashly.yml（bashly 1.4 生成参数解析），入口收敛为 src/root_command.sh
- 源码按功能域重组：config/storage/integrate/media/pipeline，消除扁平散落
- 新增零依赖测试框架 tests/（123 用例）与 CI 流水线（lint + test + build + 产物一致性）
- build.sh 支持版本单一来源注入与 --check 产物校验；新增 lint.sh（bash -n + shellcheck 零容忍）
- 删除旧单文件 media_organizer.sh 与旧扁平模块
