feat: integrate ReleaseVersion component into HelpButton

- Added `ReleaseVersion` component:
  - Displays the current CLI version, including:
    - Released version (e.g., `v0.0.11 (2024-12-19)`).
    - Unreleased version with short Git hash (e.g., `v0.0.11 + 0d6169a (2024-12-19)`).
  - Fetches version information from the `CliVersionProvider`.

- Updated `App.tsx`:
  - Initialized `cliVersion` using `import.meta.env.VITE_CLI_VERSION_*` environment variables.
  - Wrapped `ERDRenderer` with `CliVersionProvider` to provide version context globally.
