bug: App version is hardcoded to "0.0.0" instead of the real version

Summary APP_VERSION is hardcoded to "0.0.0" with a leftover TODO, so anywhere the app surfaces its version shows the wrong number. The real version is 2.2.0 (apps/studio/package.json).

Where

• apps/studio/src/shared/lib/constants.ts:4

  export const APP_VERSION = "0.0.0" // TODO: Replace with actual version or inject at build time
  

Suggested fix Inject the version at build time from package.json rather than hardcoding. With Vite you can expose it via define in vite.config, e.g. __APP_VERSION__: JSON.stringify(pkg.version), or import the version from package.json and reference it in the constant.

Steps

1. Branch: git checkout -b fix/app-version.
2. Wire the real version into APP_VERSION (build-time inject or import from package.json).
3. Verify the displayed version matches apps/studio/package.json.
4. Run yarn lint and yarn typecheck; open a PR.

Acceptance criteria

• APP_VERSION reflects the real package version, no hardcoded 0.0.0.
• TODO removed.
