Ancestor Report

Use when the user asks to generate, build, or write a genealogy report, ancestor report, ancestry report, or family tree report from a GEDCOM file — particularly one organized by generation with categorized immigrant tables (e.g., "report all my ancestors back N generations", "make a markdown report of [person]'s ancestry", "list immigrants in my tree by region", "build a colonial ancestors report"). Outputs a single markdown file with Ahnentafel-numbered generations, optional alternate family trees for FAMC conflicts, and tables grouped by region of origin and (optionally) by colonial-era status.
