[BUGFIX] Fix a "null"-rendering issue (#1575)

<!-- ELLIPSIS_HIDDEN -->


> [!IMPORTANT]
> Fixes null handling in `ParsedResponseRender.tsx` and updates
configuration files for better formatting and conditions.
> 
>   - **Bugfix in `ParsedResponseRender.tsx`**:
> - Fixes issue where `null` response was not handled, now returns
`null` instead of undefined.
> - Handles cases where `parsedResponseObj` is `null` or not an object
by rendering `RenderPromptPart`.
>   - **Configuration Changes**:
> - Adds condition `if: github.event_name == 'release'` to `build-cli`
job in `primary.yml`.
> - Corrects JSON formatting in `launch.json` by adding missing commas.
> - Updates `tsconfig.build.json` to include `src/**/*` and removes
`exclude` section.
