When running gh-make-golang estimate on a large package, the process eats up a lot of memory and CPU, and eventually dies as OS kills it.

Steps to reproduce:

$± curl -LO https://salsa.debian.org/otto/dh-make-golang/-/jobs/8033558/artifacts/raw/debian/output/dh-make-golang_0.8+git20250820.a6fe7fa-1~otto+salsaci+20250820+39_amd64.deb

Using the latest released version does not have this issue:

I suspect this might be a regression from one of the recent changes in the `estimate` command in e.g. 9910944, 364c9eb, c49bae1 or 066571e. Could @n-peugnet take a look?
