- Introduced a new boolean column `cleanCache` in the application schema to manage cache cleaning behavior.
- Updated the application form to include a toggle for `cleanCache`, allowing users to enable or disable cache cleaning.
- Enhanced application deployment logic to utilize the `cleanCache` setting, affecting build commands across various builders (Docker, Heroku, Nixpacks, Paketo, Railpack).
- Implemented success and error notifications for cache updates in the UI.
Added a new environment variable HEROKU_STACK_VERSION that can be used to specify the desired Heroku stack version.
Updated the buildHeroku and getHerokuCommand functions to use the specified stack version, or default to 24 if the environment variable is not set.
Provided information about the available Heroku stack versions and their support details, as per the documentation from the Heroku DevCenter.
