[rush] Rush 5.175.1 and pnpm 11.1.1 do not work together (build scripts issues)

[kgetz-arista]

Summary

I'm trying to upgrade to the latest version of both tools (we're currently on pnpm 10), but I'm getting stuck in a hopeless loop. It seems that Rush doesn't support pnpm 11 properly.

Repro steps

Upgrade to Rush 5.175.1 and pnpm 11.1.1 and try to rush update.

Details

When I run rush update, I get this error:

Progress: resolved 2224, reused 0, downloaded 2012, added 2005, done
[ERR_PNPM_IGNORED_BUILDS] Ignored build scripts: @arista/protobufjs@6.11.1, @parcel/watcher@2.5.6, @scarf/scarf@1.4.0, @sentry/cli@2.58.5, @tree-sitter-grammars/tree-sitter-yaml@0.7.1, core-js-pure@3.49.0, esbuild@0.27.7, esbuild@0.28.0, protobufjs@7.5.7, tree-sitter-json@0.24.8, tree-sitter@0.21.1, tree-sitter@0.22.4, unrs-resolver@1.11.1

Run "rush-pnpm --subspace default approve-builds" to pick which dependencies should be allowed to run scripts.

This already seems like an issue, because I've already added these dependencies to my pnpm config. I went through this whole issue before several months ago. See #5542 and #5683 for some context.

Anyway, I tried running the command Rush printed (rush-pnpm --subspace default approve-builds) and it "worked" in the sense that it ran the scripts, but it did not make any changes to any config files. If I subsequently run rush install or rush update, the whole process repeats itself, and the command fails again.
