Replace the two thin "docs live in …" lines with the conventions the
docs/ READMEs establish: the three document types (PRD / research note
/ decision record) with their numbering and the PRD Status lifecycle,
plus the cross-cutting rule that decision rationale stays self-contained
in the repo rather than in Gitea issue threads. Points at the per-folder
READMEs as the source of truth instead of duplicating them.
