Improvements

Platform-native dialog button order - Dialog buttons now follow each platform's convention. On Windows the confirming button (OK / Save / Apply) sits on the left; on other platforms it stays on the right.
Ctrl+F4 closes the editor on Windows - The active editor can now be closed with Ctrl+F4 in addition to Ctrl+W, matching the usual Windows convention.

Fixed inserting copied rows below (or columns to the right) so they land after the end of the selection instead of after its first row/column, and the selection no longer loses a row/column when it includes the last one. (#202)
Fixed filtering with certain LIKE patterns (such as %a%a%...%ab) freezing the app; matching is now fast and bounded.
Fixed a malformed smoothcsv:// link being able to crash or briefly freeze the app.
Fixed a security issue in how SmoothCSV handles external links.
Fixed opening smoothcsv:// links: query option values containing = no longer fail the open, and a reversed line/cell range (e.g. 10-1) now selects the same region as 1-10 instead of an odd backwards selection.
Fixed the status bar disappearing when a non-grid editor was active.
Fixed the macOS traffic light buttons drifting within the title bar when zooming in or out. They now stay properly inset and vertically centered at any zoom level.
