What

• Features as a two-column table instead of bold leads with dashes; screenshot captions without bold leads
• Gone: "You don't have to take my word for it", "Every hardware report ends up in this table", "not the tool but the checks", and the "keep it if it works for you" line that docs/compare.md already has
• The section on how RigShift is built is one sentence under Development
• Project page: the source-and-releases card states the checks without the tool note

README: 153 lines (was 160).

Closes #78
