chore(release)!: Version 3.0

[JacobCoffee]

Standing PR for the 3.0 release

Important

• Until feature freeze in 2.x, be mindful of the changes you are pulling into this branch.
• Use rebasing to bring the latest changes from main into this branch as it makes the process of merging it back into main with a merge commit when the release is due easier
• Use a merge commit without squashing when merging this branch into main to keep the history of the feature commits intact

Breaking Changes

Any breaking changes should be properly marked with ! in the conventional commits schema, e.g., fix($scope)!: fix thing but it broke stuff, feat(dtos)!: add breaking feature
