[ci-coach] ci: fail-fast Go format check and add copilot-setup-steps timeout

[github-actions]

Summary

Two small CI workflow optimizations that follow fail-fast principles and add a safety guard, with no impact on passing builds.

---

Optimizations

1. Go Format Check: Fail Fast Before Build & Test

Type: Job Step Ordering
Impact: ~1–2 minutes saved per run when formatting is wrong
Risk: Low

Changes:

• Moved the gofmt format check step to run immediately after actions/setup-go in build-go, before go mod download, go build, and go test

Rationale: Previously, a formatting violation would only be caught after downloading all Go dependencies, compiling the entire module, and running all tests. By checking format first (it requires only the Go toolchain, which is already installed by setup-go), the job fails in seconds rather than waiting 1–2 minutes for the full pipeline to complete. This is the standard "fail fast" CI pattern.

Before / After Step Order

Before:

setup-go → go mod download → go build → go test → gofmt check
```

**After:**
```
setup-go → gofmt check ← fails here immediately if unformatted
         → go mod download → go build → go test

2. copilot-setup-steps: Add timeout-minutes: 10

Type: Resource Safety
Impact: Prevents runaway runner consumption
Risk: Low

Changes:

• Added timeout-minutes: 10 to the copilot-setup-steps job in copilot-setup-steps.yml

Rationale: The job had no timeout, meaning a hung dependency install or network issue could consume a runner for the default 6-hour GitHub Actions limit. A 10-minute ceiling matches the actual expected runtime (all four language runtimes install in well under 5 minutes) while providing a clear fail signal if something goes wrong.

---

Expected Impact

• Time Savings: ~1–2 minutes per build-go run where formatting fails
• Risk Level: Low — changes only affect step ordering and add a safety timeout; no logic changes

Testing Recommendations

• Review workflow YAML syntax
• Monitor the first build-go run after merge to confirm step order is correct
• Confirm copilot-setup-steps still completes within 10 minutes

Subject: [PATCH] ci: fail-fast Go format check and add copilot-setup-steps
 timeout

- Move gofmt check before go mod download/build/test in build-go job
  so formatting failures are caught immediately without wasting time
  on dependency downloads and compilation (~1-2 min savings on failure)
- Add timeout-minutes: 10 to copilot-setup-steps job as a safety guard
  against runaway runner consumption

Thanks for flagging these optimizations, ci-coach! Both suggestions are solid:

1. Fail-fast gofmt check — moving the format check before go mod download is the classic CI fail-fast pattern. A formatting violation will now surface in seconds instead of waiting ~1–2 minutes for the full dependency/compile/test pipeline.

2. copilot-setup-steps timeout — good catch. Without a timeout, a hung network call could occupy a runner for up to 6 hours. 10 minutes is a generous ceiling that matches real-world install times while providing a clear failure signal.

I've picked these changes up and created a PR implementing both: look for a draft PR titled "ci: fail-fast Go format check and add copilot-setup-steps timeout" from the repo-assist/ci-go-format-timeout branch.
