* [Oracle] Parse sets lazily to slash importer peak memory
- Add a raw JSON scanner that splits the document into per-set byte ranges
without materializing the JSON tree
- Keep only the raw document bytes and parse one set at a time in startImport
- Take readSetsFromByteArray by value so the wizard's buffer is moved, not copied
- Clear the retained raw data in releaseSetData()/clear()
- Cover the scanner and lazy parsing with tests
Took 2 minutes
* [Oracle] Fix nesting-depth cap, tolerate unescaped control chars, lazy-parse review fixes
