Problem

Analytics is currently opt-out: ConsentManager.initialize() defaults to enabled: true, hasConsented: true, and AnalyticsConsent is never rendered, so PostHog starts on first launch without asking the user.

src/lib/analytics/consent.ts:

this.settings = {
  enabled: true,
  hasConsented: true,
};

Change

• Default to enabled: false, hasConsented: false (all four default sites, including the error fallback and deleteAllData);
• Render <AnalyticsConsent /> in the app root so first-run users are actually asked (the component already exists and already calls analytics.enable() / analytics.disable(), it just was not mounted).

AnalyticsService.initialize() only initializes PostHog when hasConsented && enabled, so with this change PostHog stays off until the user accepts.

Notes

• Users who already have opcode-analytics-settings in localStorage keep their stored choice (no forced reset).
• The Settings page already has a telemetry toggle, so users can change it later.
