docs: rename roadmap.md to macroplan.md and refresh the plan

The file is the macroplan (plus per-version scope), so rename it to match and
retitle to "Macroplan"; update all inbound links and friendly labels across the
docs. Refresh the plan while here: v0.2 gutter built, :gl pull recorded (v0.7),
command-line editing (v0.4), and the format_on_save pref (v0.5).
