Description

cspell can crash with Linter Error: readline was closed on Node 24, when using option --file-list stdin, and a large list of files. It does not crash on Node 22.

Steps to Reproduce

1. Create 10000 small text files, and a list of the files in another text file. If this doesn't repro on your system, try different numbers of files.

for i in $(seq 1 10000); do
  echo '{}' > file$i.txt
  echo file$i.txt
done > files.txt

2. Run cspell using Node 24:

$ node --version
v24.14.1

$ npx cspell@9.7.0 lint --file-list stdin < files.txt
...
9998/9998 file9998.txt 0.54ms
9999/9999 file9999.txt 0.55ms
Linter Error: readline was closed

Expected Behavior

$ node --version
v22.22.2

$ npx cspell@9.7.0 lint --file-list stdin < files.txt
...
9998/9998 file9998.txt 0.50ms
9999/9999 file9999.txt 0.51ms
10000/10000 file10000.txt 0.57ms
CSpell: Files checked: 10000, Issues found: 0 in 0 files.
