Release fixes: CLI --version, ALSA on Linux, web build via xtask, xtask version

- effectcraft-cli: support --version/-V/version (the packaging smoke tests call it).
- Linux release job installs libasound2-dev for alsa-sys; deb/rpm depend on
  libasound2/alsa-lib; Flatpak gets --socket=pulseaudio.
- packaging/web/package.sh builds with `cargo xtask web` (wasm-bindgen) and zips
  <target>/web/dist; the release job installs wasm-bindgen-cli 0.2.129.
- xtask: version.rs (ported from PhotoCraft) called helpers that don't exist here,
  so xtask didn't compile; use the local run() and wire up `cargo xtask version`.
