# In linked git worktrees, git exports an absolute GIT_DIR to hooks. Child git
# calls that run in package subdirectories (jest --onlyChanged, via turbo) then
# treat their own cwd as the top of the working tree and report thousands of
# phantom changed files, so unrelated suites run with broken module resolution.
# Unset it so each git call rediscovers the repo from its cwd — correct in both
# the main checkout and linked worktrees. GIT_INDEX_FILE stays exported so
# partial commits (git commit <paths>) still expose the temporary index to
# lint-staged.
