chore: bump obikmer to 1.1.9 and update release workflow

Bumps the obikmer crate version from 1.1.7 to 1.1.9 in Cargo.toml and Cargo.lock. Updates the Gitea release workflow to dynamically locate the Zig compiler via Python, generating musl-targeted gcc/g++ wrapper scripts installed to /usr/local/bin for static Linux cross-compilation during releases.
