xavierkandCommandCodeBot 1e2ddfb928 fix(packaging): address review findings for #44
- nfpm.yaml: type:config → config_noreplace (RPM noreplace semantics)
- nfpm.yaml: type:ghost → type:dir for /var/lib/fenris (deb compatibility)
- postinst.sh/rpm/post.sh: fix timer restart — capture running unit before
  daemon-reload so the diff actually detects changes
- README: fix Python floor to ≥3.10 (was ≥3.9, inconsistent with Makefile)
- signing-key-ceremony.md: fix stale claim about nfpm signing RPMs
  (actual path is post-build rpmsign)
- tests/conftest.py: extract shared _get_version() and _read() helpers
- tests: wire up to shared conftest helpers
- release.yml: extract VERSION once via GITHUB_OUTPUT step
