- Upgrades eslint from v8 to v9 - Upgrades all other eslint packages. We will have to do a new full-project lint, as new rules have been added - Upgrades husky from v8 to v9 - Upgrades lint-staged from v14 to v15 - Moves the old .eslintrc.cjs file format to the new eslint.config.js flat file format. Previously, we were very specific regarding which rules are applied to which files. Now that `extends` is no longer a thing, I have to use deepMerge & imports instead. This is rather uncommon and is not a documented pattern - e.g. typescript-eslint docs want us to add the default typescript-eslint rules to the top-level & then disable it in files using the disable-typechecked config. However, I hate this opt-out approach. The way I did it here adds a lot of clarity as to which rules are applied to which files, and is pretty easy to read. Much less black magic ## .eslintignore These files are no longer supported (see https://eslint.org/docs/latest/use/configure/migration-guide#ignoring-files). I moved the entries to the ignores property in the eslint config. => one less file in each package folder!
