Walkthrough

Each -large_file argument passed to zoekt-git-index is now wrapped in double quotes to prevent shell glob expansion of file pattern values (e.g., **/*.go) before the command runs.

Changes

Cohort / File(s)	Summary
Shell expansion fix packages/backend/src/zoekt.ts	Wrap -large_file pattern arguments in double quotes when constructing the zoekt-git-index command to stop the shell from expanding glob patterns provided via environment variables (e.g., ALWAYS_INDEX_FILE_PATTERNS).
