Snap package: strict core24 snap on every release, optional Snap Store upload (#413)

* Snap package: build, test and attach a strict snap to every release packaging/linux/snap/snapcraft.yaml (core24, strict, gnome extension) repackages the release's Linux tarball like the Flatpak does. The release workflow builds it for amd64 and arm64, installs it with --dangerous, models a box in the confined app on headless X11 and Wayland, and attaches solidcraft-<version>-linux-<arch>.snap plus the version-less copy. When SNAPCRAFT_STORE_CREDENTIALS is set, nightlies go to edge and release drafts to candidate, and snap-store.yml promotes candidate to stable when a release is published. The README gets a Snap badge and install line.

+# Repackage a SolidCraft Linux tarball as a snap:
+#
+#   $DIST/solidcraft-<version>-linux-<arch>.snap
+#
+# Usage: packaging/linux/snap-pack.sh [--destructive-mode] [TARBALL]
+#
+# TARBALL defaults to $DIST/solidcraft-<version>-linux-<arch>.tar.gz from package.sh. The snap is
+# built for the host architecture (x86_64 or aarch64), which must match the tarball's. Needs
+# snapcraft (`sudo snap install snapcraft --classic`) and, without --destructive-mode, LXD.
+# --destructive-mode builds on the host itself, which must be Ubuntu 24.04 (the core24 base),
+# as in CI. Install and smoke-test the result with:
+#   sudo snap install --dangerous dist/release/solidcraft-<version>-linux-<arch>.snap
+#   python3 packaging/linux/snap-smoke.py
+# Manifest: packaging/linux/snap/snapcraft.yaml.
