Build #5 got through checkout, loadConfig, and the pre_build hook,
then hit two real bugs at the actual docker build step:
1. `docker build` failed with "mkdir /root/.docker/buildx: read-only
file system" — dind-pod.yaml mounts the Harbor push-auth secret
read-only at /root/.docker, but modern docker defaults to
BuildKit/buildx, which wants to write its own state there. Forces
the classic builder via DOCKER_BUILDKIT=0 instead.
2. The subsequent error-handling itself then threw a
NullPointerException — every stage file (including untouched
legacy ones from the real devops-lib) reads env.FAILURE when
setting currentBuild.result, but nothing in this repo ever defined
it, so it was null. Defined once in homelabPipeline.groovy rather
than touching 40+ individual occurrences across every stage file.
Drops AGENTS.md, BUGS_AND_IMPROVEMENTS_REPORT.md, CLAUDE.md,
ai-blitz/*, and docs/{SECURITY.md,acronyms.md,adr/*} — leftover
documentation and task scaffolding from the original org-wide devops-
lib that don't describe this homelab's simplified single-service
pipeline. These were already missing from the working tree from
earlier cleanup; this commit just records that state.
