v0.6.2

Added

• Cancellable batch processing: when you apply a processing to several selected signals or images at once, it now runs object by object through the progress dialog, whose Cancel button (or the Esc key) stops it at the next object — keeping the results already computed. Single-object operations and aggregations (which are a single computation) are not interruptible.
• Busy indicator for long computations: a single processing that takes more than a moment (e.g. a moving median on a large image) now shows a "Computing…" dialog with an animated bar, instead of only greying the interface.
• Test data loading in Test Data plugin: the bundled Test Data plugin now offers menu actions to load a set of standard test signals and images (sine, Gaussian, dot matrix, …) directly, making it easy to explore processing features without importing external files.

Changed

• The Pyodide runtime now runs in a background worker by default, keeping the interface responsive while computations run. The previous in-thread runtime remains available as a fallback via ?runtime=main (see doc/troubleshooting.md).
