fix: quote glob patterns in zoekt-git-index to prevent shell expansion

The ALWAYS_INDEX_FILE_PATTERNS environment variable accepts glob patterns
like **/*.sum,**/*.lock. When these patterns are passed to zoekt-git-index
via Node's exec(), the shell expands them before passing to the command,
causing errors.

This fix wraps the glob patterns in double quotes to prevent shell
expansion, allowing the patterns to be passed literally to zoekt-git-index.

Fixes SOU-247
