fix: map requirements-completed frontmatter in summary-extract (#627) (#716)

Add requirements_completed field to summary-extract output, mapping
from SUMMARY frontmatter requirements-completed key. Enables
/gsd:audit-milestone cross-check to receive data from SUMMARY source.

Re-applied from #631 against refactored codebase (commands.cjs + split tests).
