Add Snap Store packaging

Publish OrcaSlicer to the Snap Store (classic confinement) on channels matching the release tiers: stable / candidate / beta / edge. The Linux build (both arches) repackages the AppImage AppDir into a snap; nightly builds go to edge, and tagged releases publish to the matching channel. Stacked on the Linux ARM64 AppImage change.

+# Classic confinement: like the AppImage, OrcaSlicer runs in the host namespace
+# and uses host libraries. This is required for full hardware/filesystem access —
+# notably the 3D mouse (SpaceMouse via the host spacenavd socket at
+# /run/spnav.sock), which no strict-confinement interface can reach.
+# NOTE: classic confinement must be granted once by the Snap Store (forum request)
+# before uploads to any channel are accepted. See snap/README.md.

+# runtime smoke tests are the real check (see snap/README.md).
