chore(vqol): rewrite README + move internal status out of public view

[byteworthy]

Summary

• README rewritten as patient-and-clinic-facing (not dev-internal-facing)
• Internal launch blockers and internal status moved to new STATUS.md
• SVG hero added (1280×200, pulse waveform graphic, dark background)
• "For patients" and "For practices" sections replace the internal "Current Status" list
• Privacy section prominent and specific
• Deploy buttons (GitHub Pages, Cloudflare, Netlify, Vercel) added
• Instrument/LSHTM note rewritten to be factual and non-alarming
• All technical detail (project structure, verification, stack) preserved

Test plan

• No internal launch blocker text in README
• STATUS.md exists and contains the moved internal content
• Hero renders on GitHub README
• Deploy buttons render and link correctly
• Instrument note present and accurate
