// Package tools 是项目的公共工具集。
//
// 每个子包都是对 GoFrame 内置组件的薄封装，
// （gmd5、gaes、gdes、guid、grand、gtime、gconv、gstr、gfile 等），
// 保持小巧且与框架风格一致。
//
// 结构：
//
//	common/tools/md5       MD5 digest helpers
//	common/tools/cryptox   AES/DES encryption with base64 output
//	common/tools/uuid      unique ID generation
//	common/tools/random    random numbers and strings
//	common/tools/timex     time formatting and computation
//	common/tools/convertx  type conversion with default fallback
//	common/tools/strx      string / naming / masking helpers
//	common/tools/slicex    generic slice utilities
//	common/tools/ip        IP address helpers
//	common/tools/filex     file system helpers
//
// 规则：
//   - Never depend on internal/ — this module must stay self-contained.
//   - Prefer reusing GoFrame built-in components over re-implementing.
//   - Keep each helper small and add a Chinese doc comment.
