Go version upgrade:

• Updated the Go version from 1.26.6 to 1.27.0 in .devcontainer/Dockerfile, Dockerfile, and all GitHub Actions workflow files (master.yml, release.yml, re-release.yml, sonar.yml) to standardize on the latest Go release. [1] [2] [3] [4] [5] [6]
• Updated the go.mod file to specify go 1.27.0.

Dependency upgrades and cleanup:
