3/8 ci: split monolithic workflow into build, sign, release stages

build.yml   — builds PDFs, uploads artifact, no secrets required
sign.yml    — hashes (SHA-256 + BLAKE2b) and GPG-signs, triggered via
              workflow_run after build or manually with a build_run_id
release.yml — downloads artifacts, uploads to VirusTotal, publishes
              tagged GitHub Release with all 12 assets attached

All three chain automatically on push to main. Each can be re-run or
triggered independently against any historical run.
