All files have `rwx` permissions

@vgeorge am not sure if this is a huge deal, but does seem a little odd for all files to have executable permissions:

```
$ ls -lah
total 256K
drwxrwxr-x 8 sanj sanj 4.0K Oct 8 11:53 .
drwxr-xr-x 14 sanj sanj 4.0K Oct 8 11:53 ..
drwxrwxr-x 3 sanj sanj 4.0K Oct 8 11:53 app
drwxrwxr-x 2 sanj sanj 4.0K Oct 8 11:53 .circleci
drwxrwxr-x 2 sanj sanj 4.0K Oct 8 11:53 config
-rwxrwxr-x 1 sanj sanj 534 Oct 8 11:53 .editorconfig
-rwxrwxr-x 1 sanj sanj 281 Oct 8 11:53 .eslintrc
drwxrwxr-x 8 sanj sanj 4.0K Oct 8 11:53 .git
-rwxrwxr-x 1 sanj sanj 11 Oct 8 11:53 .gitattributes
-rwxrwxr-x 1 sanj sanj 2.8K Oct 8 11:53 .gitignore
-rwxrwxr-x 1 sanj sanj 423 Oct 8 11:53 index.js
-rwxrwxr-x 1 sanj sanj 1.1K Oct 8 11:53 LICENSE
-rwxrwxr-x 1 sanj sanj 3 Oct 8 11:53 .nvmrc
-rwxrwxr-x 1 sanj sanj 1.4K Oct 8 11:53 package.json
-rwxrwxr-x 1 sanj sanj 186K Oct 8 11:53 package-lock.json
-rwxrwxr-x 1 sanj sanj 589 Oct 8 11:53 README.md
drwxrwxr-x 2 sanj sanj 4.0K Oct 8 11:53 test
drwxrwxr-x 2 sanj sanj 4.0K Oct 8 11:53 .vscode
```

Ideally regular files would just be `-rw-rw-r` ? Am happy to fix if this is unintentional.
