Please address the comments from this code review:

## Overall Comments
- Passing `&lightweightData` to `compositor->overrideSelection()` risks a dangling pointer if the compositor stores the `QMimeData*` beyond the call; consider ensuring `overrideSelection` copies the data or allocating a heap-owned `QMimeData` with a clear ownership model.
- Filtering strictly on `"text/plain"` and `"text/html"` MIME types may miss common variants like `"text/plain;charset=utf-8"`; consider using `hasFormat` or a more flexible match (e.g., prefix or `startsWith("text/plain")`) if those formats should also be supported.

**issue (bug_risk):** Avoid passing a pointer to a stack-allocated QMimeData into overrideSelection.

`lightweightData` is a stack object whose address is passed to `overrideSelection`. This is only safe if `overrideSelection` is strictly synchronous and never stores the pointer. To avoid lifetime issues, either change `overrideSelection` to take `QMimeData` by value/const reference and copy as needed, or allocate `lightweightData` on the heap with well-defined ownership.
