Mirror OpenAM #1064 and #1065 for the OpenIG workflows: - build.yml: keep the full Java matrix (11, 17, 21, 25, 26) on ubuntu-latest, but only exercise the min/max JDKs (11 and 26) on macos-latest and windows-latest via matrix include, cutting the build-maven matrix from 15 jobs to 9 while keeping OS smoke coverage on the JDK edges. - Add a top-level concurrency group keyed on workflow + ref to every workflow: build.yml cancels the superseded in-progress run (cancel-in-progress=true), while deploy.yml and release.yml queue instead (cancel-in-progress=false) so an in-flight Maven Central publish, tag push or GitHub release is never aborted midway.

Summary
Mirrors OpenAM #1064 and #1065 for the OpenIG GitHub Actions workflows.
1. Reduce CI build matrix on macOS/Windows to min/max JDK (
build.yml)The
build-mavenmatrix was a full cross-product of 5 JDKs × 3 OSes = 15 jobs. This reduces it to 9 jobs by only exercising the minimum and maximum supported JDKs on macOS and Windows:11, 17, 21, 25, 26(also feeds thebuild-dockerjob via theubuntu-latest-11artifact)11and26only (viainclude)11and26only (viainclude)Because the
includeentries useosvalues that don't match the baseos: [ ubuntu-latest ], GitHub Actions creates them as new combinations rather than expanding existing ones, so JDK 17/21/25 no longer run on macOS/Windows. Full coverage is retained on Linux.2. Add concurrency groups to CI workflows
Add a top-level
concurrencygroup keyed on${{ github.workflow }}-${{ github.ref }}so redundant runs on the same ref collapse instead of piling up.cancel-in-progressbuild.ymltruedeploy.ymlfalserelease.ymlfalserelease:prepare/release:perform, tag push, GitHub release).codeql.ymlis intentionally not touched here (handled separately, as in OpenAM #1065).
