Reset velocity on borders (#8)

* Refactor game structure: move paddle logic to game module and update viewport constants for default values

* Add ball module and implement ball movement system; refactor paddle creation

* Make BALL_RADIUS and PADDLE_SIZE public; adjust paddle size calculation

* Refactor ball radius calculation to use PADDLE_SIZE; update wall collision logic accordingly

* Add missing allow attribute for dead code in ScalingStrategy enum

* Implement ball physics and collision systems; add walls module and update game structure

* Reorder update systems to ensure viewport updates occur alongside game logic

* Add ball holding and launching mechanics; clean up build tasks

* Refactor wall creation logic into a helper closure for improved readability and maintainability

* Update workflow to trigger on pull requests for Rust files and Cargo.toml

* bump version to 0.6.0 in Cargo.toml

* Super-Linter: Fix linting issues

* QoL Refactoring of the paddle movement system to reset velocity on direction change when hitting walls

* Bump version to 0.7.0 in Cargo.toml
