refactor(db)!: replace SQLite Driver with glebarez/sqlite to avoid CGO

[PIKACHUIM]

Description / 描述

将 SQLite 数据库驱动从基于 CGO 的 gorm.io/driver/sqlite（底层依赖 mattn/go-sqlite3）替换为纯 Go 实现的 github.com/glebarez/sqlite（底层依赖 modernc.org/sqlite），彻底消除对 CGO 的依赖，实现真正的纯 Go 跨平台编译。

主要变更：

• internal/bootstrap/db.go：将 SQLite 驱动导入从 gorm.io/driver/sqlite 替换为 github.com/glebarez/sqlite
• go.mod：新增 github.com/glebarez/sqlite v1.11.0，移除 github.com/mattn/go-sqlite3（CGO 依赖），同步升级 gorm.io/gorm v1.25.11 → v1.30.0
• go.sum：更新依赖哈希

Motivation and Context / 背景

原有的 gorm.io/driver/sqlite 驱动底层依赖 mattn/go-sqlite3，该库需要通过 CGO 编译 C 代码，导致：

1. 交叉编译困难：CGO 交叉编译需要配置对应目标平台的 C 编译器工具链，增加了构建复杂度
2. 构建环境要求高：CI/CD 环境需要安装 GCC 等 C 编译器
3. 纯 Go 构建不可用：无法使用 CGO_ENABLED=0 进行纯 Go 静态编译

github.com/glebarez/sqlite 是 gorm.io/driver/sqlite 的纯 Go 替代品，底层使用 modernc.org/sqlite（SQLite 官方 C 代码通过工具自动转译为 Go 代码），与 GORM 完全兼容，无需任何 CGO 即可完成编译。

How Has This Been Tested? / 测试

• 使用 CGO_ENABLED=0 go build 验证纯 Go 编译成功
• 启动服务，使用 SQLite 数据库类型（sqlite3）验证数据库连接正常
• 验证开发模式（--dev）下内存数据库（file::memory:?cache=shared）正常工作
• 验证 WAL 模式（_journal=WAL&_vacuum=incremental）下数据库读写正常
• 验证 MySQL、PostgreSQL 数据库类型不受影响

Pull request overview

This PR switches the project’s SQLite GORM dialect from the CGO-based gorm.io/driver/sqlite (mattn/go-sqlite3) to the pure-Go github.com/glebarez/sqlite (modernc.org/sqlite) to enable CGO_ENABLED=0 builds.

Changes:

• Updated DB bootstrap code to open SQLite connections via github.com/glebarez/sqlite.
• Updated Go module dependencies, including adding github.com/glebarez/sqlite and bumping gorm.io/gorm to v1.30.0.
• Refreshed dependency hashes in go.sum.

File	Description
internal/bootstrap/db.go	Switches the SQLite dialect import/usage to github.com/glebarez/sqlite.
go.mod	Adds github.com/glebarez/sqlite, upgrades GORM, and adjusts indirect deps (but still retains CGO SQLite deps).
go.sum	Updates module sums to reflect the dependency graph changes.
