URL: https://github.com/apache/texera/pull/5899
### What changes were proposed in this PR?
Pin behavior of three previously-untested file scan source descriptors in
`common/workflow-operator`. No production-code changes.
| Spec | Source class | Tests |
| --- | --- | --- |
| `CSVOldScanSourceOpDescSpec` | `CSVOldScanSourceOpDesc` | 6 |
| `JSONLScanSourceOpDescSpec` | `JSONLScanSourceOpDesc` | 5 |
| `ArrowSourceOpDescSpec` | `ArrowSourceOpDesc` | 5 |
**Behavior pinned**
| Surface | Contract |
| --- | --- |
| `operatorInfo` | exact name + description; Data Input group; 0 inputs / 1
output |
| field defaults | per-type defaults (CSVOld `customDelimiter=Some(",")`,
`hasHeader=true`; JSONL `flatten=false`; encoding `UTF_8`; `limit`/`offset`
`None`; `fileTypeName`) |
| `sourceSchema()` | `null` before a file is resolved (IO-free
short-circuit) |
| `getPhysicalOp` | wires `OpExecWithClassName` for the matching `*OpExec`,
no input port / one output port, IO-free; CSVOld falls back to a comma on an
empty delimiter; JSONL is parallelizable |
| Round-trip | config fields preserved through the polymorphic `LogicalOp`
base |
### Any related issues, documentation, discussions?
