Keep the Segment-Based Voronoi Reproducers

The gapfill, weirdness and NaN reproducers go through Orca's repairing VoronoiDiagram once they use it instead of raw boost, so they are converted rather than deleted. Only the two point-input reproducers, which the wrapper neither checks nor repairs, are removed.
Include Model.hpp in the fff_print Test Helpers

HanifKoh	d3699dd9f6	Keep Python Bytecode out of the Bundled Python Home (#16550 ) * Keep Python Bytecode out of the Bundled Python Home The bundled stdlib ships .pyc files that are stale against their sources: they are compiled when the Python deps are installed, and the copy into the app does not keep the sources' mtimes. CPython then recompiles every module it imports and writes the result next to the source. A drag-installed macOS app rewrites files inside its own bundle on first launch, so its signature no longer verifies, and read-only installs (AppImage, Flatpak, Program Files) recompile the same modules on every launch. Point pycache_prefix at <data_dir>/python/pycache so the interpreter reads and writes bytecode there. The bundle is never written, the cache survives between launches, and the data directory is already a plugin read/write root. * Drop Cached Bytecode Through the Interpreter in the Module Release Test	2026-10-19 13:48:53 +08:00
