Struct LockFile 

pub struct LockFile {
    pub version: u32,
    pub migrations: Vec<LockEntry>,
}

Migration lock file for tamper detection.

Stores checksums of all migrations to detect if they’ve been modified after being applied. This prevents data integrity issues from migrations being changed retroactively.

Fields

version: u32

Version of lock file format

migrations: Vec<LockEntry>

Locked migrations (stored as vec for TOML compatibility)
