build: bump Go to 1.27

[madhavilosetty-intel]

Summary

Bumps the module and CI to Go 1.27, aligning with the golang:1.27-alpine image the Docker build already uses. The golang.org/x/crypto 0.56.0 update comes along (it requires Go >= 1.26).

Changes

• go.mod: go 1.25.0 -> 1.27.0 (and x/crypto v0.55.0 -> v0.56.0)
• .github/workflows/ci.yml: test matrix 1.25.x -> 1.27.x
• .github/workflows/release.yml: license-scan 1.25.1 -> 1.27.x
• README.md / CLAUDE.md / copilot-instructions.md: Go note -> 1.27+

🟡 Changes recommended

The repo’s release workflow still pins Go 1.25.1 for the license-scan step, which will fail once go.mod requires Go 1.26.0.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Updates the project’s minimum Go version and dependency graph to address security findings by upgrading golang.org/x/crypto, and aligns CI to build/test with the new Go baseline.

Changes:

• Bump golang.org/x/crypto from v0.55.0 to v0.56.0 (and regenerate go.sum entries).
• Raise go.mod module directive from go 1.25.0 to go 1.26.0.
• Update CI workflow to install/use Go 1.26.x (formatting job and test matrix).
