dp-data 0.4.6

This release corrects Australia's shared knowledge checklist and preserves the distinction between its initial combined “None / Don't know” option and the substantive exit answer “Nothing will change.”

• Give the initial combined option zero credit in both retained batteries. Score the exit answer against the unchanged answer key. The twelve-item baseline mean falls 3.75 percentage points; the ten-item exit mean rises 3.20 points among the same 347 participants.
• Retain original answers and the combined source reason, with a nullable integer n_none_or_dk count separate from literal DK. Version the affected definitions and declare their source dependencies.
• Rebuild dependent respondent, peer, group and poll measures centrally. Attendance, group assignments, attitudes, demographics and other polls are unchanged. All earlier approved corrections remain recorded.
• Restore 52 omitted issue links in the poll metadata and decision register. Preserve unavailable-source and instrument limitations in the existing poll documentation.

Downstream projects must update their data pin and regenerate knowledge estimates explicitly. Attitude model inputs remain unchanged; the dp-distortions migration remains an unmerged PR.
