jwright c1db5cec86 M4: security pass — strict CSP, header split, build-time scan
All JS moved to external /site.js → script-src 'self' with no inline JS,
hashes or eval. Full header set via nginx (CSP, nosniff, frame-deny,
referrer, permissions, COOP/CORP); HSTS stays at the CF edge. Shared
headers include avoids the location add_header reset footgun. Build-time
secret/inline-script/third-party scan gate. SECURITY.md documents posture.
