Previously the release workflow updated Cargo.toml's version via sed
but never refreshed Cargo.lock, leaving it one version behind after
every release. Add cargo update for the openconcho package to the
prepareCmd, and add Cargo.lock to @semantic-release/git assets so it
ships in the release commit.
Also bumps the lagging 0.5.1 -> 0.5.2 lockfile entry that the
0.5.2 release missed.
Adds a `tauri` task to turbo.json with dependsOn ["^build"] so that
desktop#tauri automatically triggers web#build first via the workspace
dependency graph. The tauriScript routes tauri-action through turbo
rather than invoking tauri directly, eliminating the need for an
explicit build step.
