fix: scope validate-el.sh hook to in-project files

The PostToolUse hook tried to byte-compile every .el file edited, including ones outside the chime project. Out-of-project files typically require packages that aren't on the hook's -L paths, so validation failed for unrelated reasons. Exit 0 when the edited file isn't under $PROJECT_ROOT.
