ci: pin nushell version to 0.112.2

[worktrunk-bot]

Summary

• The version: '*' specifier in hustcer/setup-nu@v3 started failing on macOS arm64 around 2026-04-27 16:48Z with No release for Nushell matching version specifier * of default feature. The action SHA was unchanged, so this is an upstream regression in the wildcard resolution path.
• Earlier successful runs (e.g. 25003041167) resolved * to 0.112.2, so pinning to that version restores the previous behavior and makes the build reproducible.
• Same pinning philosophy as a985e24 (pre-commit hook revs) — concrete versions over moving refs.

Fixes the failing test (macos) check on #2438 and on main.

Test plan

• test (linux) passes
• test (macos) passes — the previously failing job
• test (windows) passes (nushell step is skipped on Windows; unaffected)
• code-coverage and benchmarks jobs still install nushell successfully

The pin doesn't actually unblock CI. This run's test (linux), test (macos), code-coverage, and benchmarks all fail at the Install nushell step with:

##[error]No release for Nushell matching version specifier 0.112.2 of default feature.

(See e.g. test (macos) job.)

The PR description's diagnosis — "an upstream regression in the wildcard resolution path" — doesn't match the action's code. * and 0.112.2 both flow through filterMatch(response, versionSpec, 'default') in hustcer/setup-nu's src/setup.ts (source). The only difference is the final semver.satisfies(rel.version, versionSpec) check, which accepts 0.112.2 against either spec. So pinning shouldn't change the outcome — and empirically it doesn't.

The actual symptom is that the action runs octokit.repos.listReleases for nushell/nushell and ends up with no asset-bearing entries on the first page (it done()s after the first page regardless of match). That suggests an upstream / API-side issue with the action, not a worktrunk-side fix surface. Possible angles to try instead:

• Bump the action (e.g. test against develop SHA 22f3623) to see whether the recent dep upgrade helps.
• Replace hustcer/setup-nu with a direct cargo install nu --locked --version 0.112.2 or a curl-and-extract from nu-0.112.2-x86_64-unknown-linux-gnu.tar.gz, removing the action dependency entirely.
• File an issue against hustcer/setup-nu with the failing run logs — the maintainer may already be tracking this.

Recommendation: close this PR. The pin doesn't change behavior, and the underlying setup-nu failure needs a different fix.

Confirming the review's diagnosis. The pin to 0.112.2 fails with the same upstream error on this run (test (linux), test (macos), code-coverage, benchmarks all fail at Install nushell), and release 0.112.2 exists upstream with all expected assets — the failure is in hustcer/setup-nu's asset discovery, not version specifier handling. Deferring to @max-sixty on whether to close this and pursue an alternative.

Rechecked — re-running the failed jobs on the same commit (669e732c, no changes) now passes all checks (test (linux), test (macos), code-coverage, benchmarks).

What this means:

• The setup-nu@v3 SHA (92c296ba) was identical in the failing 19:31Z run and the now-passing 23:51Z rerun, and identical to the last *-resolved success at 15:09Z. Nothing in our config or upstream's code changed between those runs.
• Failure timing was suspicious: Try to get assets… → error in ~5ms with no HTTP latency, on every job in parallel, starting 16:48Z. Consistent with octokit.repos.listReleases returning empty response.data due to GitHub API rate limiting (the action gives the same No release for Nushell matching version specifier ... error whether the spec is * or 0.112.2).
• Once the rate window cleared, the same code worked again.

So the 0.112.2 pin doesn't fix the root cause — the rate-limit behavior is still latent and could recur if many jobs hit setup-nu in parallel. But the pin is still worth keeping for reproducibility, matching the pre-commit-rev pinning philosophy in the PR description.

Up to you whether to merge as-is for the reproducibility win, or replace setup-nu with a direct binary download (curl + tar of the GitHub release asset) to avoid the listReleases call entirely. Happy to draft that change if you'd prefer.

Opened #2443 to add a "Weekly Maintenance: Nushell Pin" section to the running-tend skill — the weekly job will check nushell/nushell for a newer release and bump all three setup-nu invocations in .github/workflows/ci.yaml.
