feat(server/db): 数据层多库支持(1/4)— 连接分派 + 双方言迁移管线
- config 增 DB_DRIVER(mysql 默认 | sqlite);DSN 对 sqlite 为文件路径
- db.OpenDriver 按驱动分派:sqlite 用 modernc(纯 Go 免 CGO)+ WAL/
busy_timeout/foreign_keys/_txlock=immediate;mysql 路径不变
- store.Open 分派;mysql 保留 UTC/collation 断言,sqlite 跳过
- 迁移拆 migrations/{mysql,sqlite}/ 双套,embed 双 FS,migrate 按驱动选源
与 golang-migrate 驱动;修复 m.Close() 误关调用方 *sql.DB 的坑
- cmd/migrate 串入 DB_DRIVER;集成测试 MigrateUp 签名更新
- 新增 SQLite 时间往返 smoke 测试与端到端迁移测试(免 docker)

feat(1e): config PANGOLIN_ prefix + store.Open UTC DSN + go:embed migrations (tsk_zRA6fGU1JuHj)
- internal/config: rewrite Config with PANGOLIN_ prefix fields
(HTTPAddr, AdminAddr, GRPCAddr, MySQL DSN/fields, RedisAddr,
AutoMigrate, JWTSecret placeholder, WebhookSecret); Load() replaces
FromEnv(); missing required MySQL vars return named-field error.
- internal/store/mysql.go: single Open(cfg) entry point; uses
mysql.ParseDSN to structurally override ParseTime=true, Loc=UTC,
Collation=utf8mb4_unicode_ci, Params[time_zone]='+00:00'; asserts
SELECT @@session.time_zone=+00:00 after Ping (startup fatal).
- migrations/embed.go: //go:embed *.sql exposes var FS embed.FS.
- internal/store/migrate.go: MigrateUp/MigrateDown/MigrateVersion
backed by golang-migrate iofs source + mysql driver; ErrNoChange
treated as success.
- cmd/migrate/main.go: filled — up/down/version subcommands, reads
config.Load() + store.Open.
- cmd/server/main.go: startup sequence Load → store.Open (UTC assert)
→ MigrateUp (if PANGOLIN_AUTO_MIGRATE=true) → HTTP listen;
structured slog output at each step.
- internal/store/mysql_test.go: pure-function unit tests for buildDSN
(empty-fields case + conflicting params overridden case); both pass.
- internal/store/mysql_integration_test.go: //go:build integration;
testcontainers mysql:8 — UTC assertion + MigrateUp idempotency.
