Phase 1-6 of refactoring plan: - VFS abstraction (VfsBackend trait + LocalFs + OpenFlags builder) - DataProvider trait (SqliteProvider + PgProvider, SFTPGo-compatible) - Config refactoring (AppConfig unified sections, env overrides) - SSH handlers (sftp/scp/rsync) migrated to VFS + DataProvider - SSH public key authentication (Ed25519 signature verification) - SSH stderr → CHANNEL_EXTENDED_DATA support - Web auth uses DataProvider instead of direct SQL - User home directory from provider (per-user isolation) - PostgreSQL auth provider for SFTPGo compatibility
