ExTauri.Sidecar.Release (ex_tauri v0.2.0)

Sidecar shim that builds a standard (non-Burrito) Elixir release and execs it.

Slower than ExTauri.Sidecar.DevServer because it builds a release, but it exercises release boot, runtime config, and migrations — useful for catching problems that only surface in a packaged build without waiting for a full Burrito production build.
