Add distro/ubuntuCore for UC26 snap and image builds.

Centralize salmanoff snapcraft, dangerous-model image scripts, and QEMU workflow so UC26 can be reproduced from the SMO repo without ubuntu-core-practice. Co-authored-by: Cursor <cursoragent@cursor.com>

+Usage: build-snap.sh [OPTIONS]
+
+Build salmanoff snap with snapcraft (source: SMO repo root via local snapcraft.yaml).
+
+Options:
+  --refetch-source  Clean salmanoff part before pack (re-copy tree + submodules)
+  --clean           Remove all snapcraft parts/prime/stage before building
+  --lxd             Use LXD cleanroom instead of --destructive-mode
+  -h, --help        Show this help
+
+Prerequisites:
+  snap install snapcraft --classic
+  For --lxd on core26: LXD outbound internet (run: sudo scripts/fix-lxd-network.sh)
+  For --destructive-mode: run on Ubuntu 26.04 or use --lxd
