Notate v0.1.7

• fix: web build
• usenotate.app: the site replaces the redirect
• README screenshots: the annotate and frames-mode captures the placeholders promised
• Recording pill text speaks the discard button's grammar — solid systemRed on glass (reddish-white was mush on light-mode glass), reddish-white kept for classic where the pill is deep red; Prefs.classicChrome names the fallback-rendering check
• Onboarding proves capture; restored recordings open in seconds
