v4.8.0

Added

• Reboot fingerprint corpora for current Linux (#37): el8, el9, el10
  (captured on AlmaLinux), fedora44, debian12, debian13,
  ubuntu22.04, ubuntu24.04, ubuntu26.04, opensuse-leap16, arch
  and alpine. The 2009–2011 corpora never matched a systemd journal, so
  --fingerprint did nothing on a modern host. Each corpus has a second,
  independent reboot in test/data/verify/ that must name it first. Rocky
  and CentOS Stream verify the elN corpora, and Fedora 43 and Alpine 3.23
  verify the newest release's corpus.
• tools/fingerprints/refresh.py and the weekly fingerprints.yml
  workflow keep the reboot corpora current, the way Dependabot keeps
  dependencies current (#37). Each supported release is booted from its
  own cloud image under QEMU/KVM and its reboot captured and scrubbed. A PR
  opens when a release is new, when its reboot no longer matches its
  corpus, or when it reaches end of life.

Removed

• petit/data/fingerprint_library/, the 2009–2011 per-machine reboot logs
  the old corpora were merged from by hand. Nothing read them. Corpora now
  come from tools/fingerprints/refresh.py, and each one's independent
  second capture is kept in test/data/verify/.
