chore: bump obikmer to 1.1.6 and automate git tagging

Bumps the obikmer crate version from 0.1.4 to 1.1.6 in Cargo.toml and Cargo.lock. Updates the Makefile release target to automatically extract the version, create a Git tag, and push it to the remote repository, extending the existing workflow with standard Git publishing steps.
