chore(hooks): drop PROJECT_ROOT guard from validate-el.sh

The PROJECT_ROOT guard skipped any .el file outside the project on the theory that out-of-tree files are owned by their own project's hooks. In practice, when I edit an .el file in another repo from a Claude session in this one, the other project often doesn't have its own hook running, so the file was getting no validation at all. I dropped the guard so any .el file edited from a Claude session here gets validated, regardless of which repo it lives in.
