Method plan

crates/paimon/src/table/table_scan.rs:373–379

Plan the full scan: resolve snapshot (via options or latest), then read manifests and build DataSplits. Time travel is resolved from table options: - only one of `scan.version`, `scan.timestamp-millis` may be set - `scan.version` → tag name (if exists) → snapshot id (if parseable) → error - `scan.timestamp-millis` → find the latest snapshot <= that timestamp - otherwise → read the latest snapshot
