v2.30.5

Changed

• Umbrella == pin bumps to PyPI latest (PS-170 freshness sweep).
  scitex-writer 2.23.0→2.24.1 (post-compile fail-loud verification gate +
  clew verify gate + markers/colophon — the fix for the figure-less-PDF
  incident, so scitex[writer] consumers get the gate), scitex-dev
  0.20.1→0.21.0 (the unified compliance-linter trio: figure-lint v1 +
  raw-import research-ERROR + --new-only baseline gate), scitex-clew
  0.2.18→0.2.22.
