[BUG] HAS_BROKEN_FSTAT_FOR_ZIP_FDS version gate should include Node 24.15+ #7103
Description
What's the problem?
PR #7070 fixed the EBADF: bad file descriptor, fstat error for Node 25.7+ by reading CJS source of zip files instead of letting Node fstat the fake fd. However, the version gate only checks for Node >= 25.7:
export const HAS_BROKEN_FSTAT_FOR_ZIP_FDS = major > 25 || (major === 25 && minor >= 7);The same breaking change from nodejs/node#61769 (lib: reduce cycles in esm loader and load it in snapshot, commit ad1078c0) was backported to Node v24.15.0, causing the identical EBADF error on that version.
Confirmed by checking the commits between v24.14.1 and v24.15.0 — PR nodejs/node#61769 is included.
Reproduction
$ node --version
v24.15.0
$ yarn --version
4.14.0
$ yarn install

Works fine on Node v24.14.1, fails on v24.15.0.
Suggested fix
Widen the version gate in packages/yarnpkg-pnp/sources/esm-loader/loaderFlags.ts to also cover Node 24.15+:
export const HAS_BROKEN_FSTAT_FOR_ZIP_FDS = major > 25 || (major === 25 && minor >= 7) || (major === 24 && minor >= 15);

Indeed I completely forgot this would need to be updated. This is fixed in 4.14.1

Is this still happening to anyone else with yarn 4.14.1 on node v24.15 and >=25.7?
I have to set my engines.node to
>=18.0 <24.15 || >=25.0 <25.7and use a strict node version check script in my.yarnrc.ymlto guarantee compatibility without confusing errors.The following error occurs when running
mochawithyarn.Mocha is its latest version,

Still facing same with yarn version 4.14.1 and node 24.15.0.
`# This file contains the result of Yarn building a package (unrs-resolver@npm:1.11.1)
Script name: postinstall
node:fs:391
const stats = binding.fstat(fd, false, undefined, true /* shouldNotThrow */);
