Feat: Add configurable thread limit for parallel operations

Adds a "Threads" setting to the UI, allowing users to control the throttle limit for parallel tasks like driver and application processing. This introduces a new textbox in the build options and updates the parallel processing function to use this configurable value instead of a hardcoded one. Input validation is also added to ensure the threads value is a valid integer and is at least 1. The new setting is integrated into the configuration save/load functionality.
