Fixed QueryAsync header handling in facade static class

[michelebastione]

Inverted the hasHeader flag before forwarding it to the Excel and CSV importers from the MiniExcel facade class because their APIs use the opposite semantics.

Resolves #1007

📝 Walkthrough

Walkthrough

The generic QueryAsync<T> overloads for paths and streams now pass the inverted hasHeader value to XLSX and CSV importers. Stream overloads still preserve the input stream.

Changes

QueryAsync header forwarding

Layer / File(s)	Summary
Invert header flag for importers src/MiniExcel/MiniExcel.cs	The path-based and stream-based generic QueryAsync<T> overloads now pass !hasHeader to XLSX and CSV importers. The stream overload retains leaveOpen: true.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to de927

Generic asynchronous typed queries now correctly map header handling to the importer APIs for both file paths and streams, without changing stream ownership. No current merge-blocking risk remains.
