MeshChatX/scripts/sync_version.js

/**
 * Single source of truth: set "version" in package.json, then run:
 *   pnpm run version:sync
 *
 * Writes: meshchatx/__init__.py (__version__), meshchatx/src/version.py, pyproject.toml [project].version,
 * meshchatx/src/backend/data/THIRD_PARTY_NOTICES.txt (reticulum-meshchatx line only),
 * README + lang README "current version" lines, docs/en/platform-guides/raspberry-pi.md,
 * meshchatx/src/frontend/public/meshchatx-docs/en/platform-guides/raspberry-pi.md,
 * meshchatx/src/backend/data/licenses_backend.json (reticulum-meshchatx entry),
 * android/app/build.gradle,
 * pipx example, packaging/arch/PKGBUILD pkgver / printf fallback,
 * then runs scripts/bake_build_meta.js (git commit / channel overlay).
 *
 * __version__ lives in meshchatx/__init__.py so Chaquopy/Android (which may not ship loose .py
 * data files next to bytecode) always has a resolvable version. src/version.py stays for packaging and tools.
 * The build script runs version:sync automatically.
