Merge f7d432abd3 into 861716fbe3

The create-story template ended with an empty File List section,
providing no guidance on format. The dev-story workflow expects
structured File List entries (new/modified/deleted with paths)
and a Change Log section, but the template included neither.

Adds table format with action/path columns for File List and
date/summary columns for Change Log, matching the dev-story
workflow's expectations.

Fixes #1789
