## Summary
Fixes two CI issues:
### 1. Deploy workflows broken since PR #1034 (all staging deploys
failing)
The deploy-staging and deploy-production workflows install Go using the
**root** `go.mod`, but then build Pulumi infrastructure code from the
`deploy/` directory which has its own `go.mod`.
This started failing when PR #1034 (`build(deps): bump
github.com/pulumi/pulumi/sdk/v3 from 3.220.0 to 3.225.1 in /deploy`)
bumped `deploy/go.mod` from Go 1.24.11 to **Go 1.25.6** — a version
newer than the root module's Go 1.24.13. Every staging deploy since that
merge (Mar 6) has failed with:
```
go: go.mod requires go >= 1.25.6 (running go 1.24.13; GOTOOLCHAIN=local)
```
The last successful deploy was commit cb4807a on Mar 1, before the Go
version bump.
**Fix**: point `go-version-file` in both deploy workflows at
`deploy/go.mod` instead of the root `go.mod`.
### 2. `govulncheck` failing due to Go stdlib vulnerabilities
Five new Go stdlib vulnerabilities (GO-2026-4599 through GO-2026-4603)
were published on Mar 5-6 affecting Go 1.24.13, fixed in Go 1.25.8.
These cause `govulncheck` in the CI pipeline to fail.
**Fix**: bump root `go.mod` from Go 1.24.13 to Go 1.25.8.
## Test plan
- [ ] CI pipeline passes (govulncheck, build, lint, tests)
- [ ] Verify the deploy-staging workflow passes on the next push to main
after merge
