* refactor: explicit types for validate * refactor: explicit return types for ui-components * refactor: use exec instead of match * refactor: add lots more boundary types * refactor: more eslint warnings * refactor: more explicit exports * refactor: more explicit types * refactor: even more explicit types * fix: relax type contrainsts for superblock-order * refactor: final boundaries * refactor: avoid using 'object' type * fix: use named import for captureException This uses TypeScript (which works) instead of import/namespace (which doesn't) to check if captureException exists in sentry/gatsby (it does)
