This pull request updates the project dependencies to their latest patch and minor versions, mitigating a newly discovered vulnerability in the Go standard library (crypto/tls) by upgrading the Go version to 1.26.5.

Changes included:

• Updated target Go version from 1.26.4 to 1.26.5 in go.mod, Dockerfile, and GitHub Action workflows (codeql.yml, go-ci.yml, release.yml) to mitigate GO-2026-5856.
• Updated dependencies in go.mod and go.sum to their latest minor and patch versions.
• Verified that the build and tests pass successfully with the updated dependencies.
