sqlx 连接池配置（L2 调优层）

不修改 sz-orm 上游，在 sz-rust-orm-facade 层提供便捷配置预设。

Fields

max_connections: u32

最大连接数

min_connections: u32

最小空闲连接数

acquire_timeout: Duration

获取连接超时

idle_timeout: Duration

空闲连接超时

max_lifetime: Duration

连接最大生命周期

Implementations

impl SqlxPoolConfig

pub fn from_env() -> Self

从环境变量读取配置

环境变量：

• DB_POOL_MAX：最大连接数（默认 10）
• DB_POOL_MIN：最小空闲连接数（默认 0）
• DB_POOL_ACQUIRE_TIMEOUT：获取超时秒数（默认 30）
• DB_POOL_IDLE_TIMEOUT：空闲超时秒数（默认 600）
• DB_POOL_MAX_LIFETIME：最大生命周期秒数（默认 1800）

pub fn for_high_concurrency() -> Self

高并发预设：max=50, min=5, acquire=10s, idle=300s, max_lifetime=1800s

pub fn for_low_latency() -> Self

低延迟预设：max=20, min=10, acquire=5s, idle=120s, max_lifetime=600s

pub fn to_orm_pool_config(&self) -> PoolConfig

转换为 sz_orm_core::PoolConfig
