Greptile Summary

This PR implements two major architectural improvements to enhance the user experience on self-hosted deployments:

1. Middleware-based Authentication Redirects: The redirect logic has been moved from Next.js config to middleware, implementing intelligent session-aware routing. For self-hosted deployments (isHosted = false), the root path now redirects authenticated users directly to /workspace and unauthenticated users to /login, bypassing the landing page entirely. This creates a streamlined experience for private/enterprise deployments where marketing content is unnecessary.

2. Telemetry Consent Dialog Removal: The entire telemetry consent workflow has been eliminated, including:

• Removal of the TelemetryConsentDialog component from the root layout
• Database migration to drop the telemetry_notified_user column from the settings table
• Cleanup of telemetry notification tracking from the general settings store and API endpoints
• Updated TypeScript interfaces to remove consent-related properties

The changes maintain core telemetry functionality (users can still enable/disable in settings) while removing the consent dialog that previously interrupted the user onboarding flow. The middleware approach provides better performance by handling redirects before React components render, and centralizes authentication logic in a more appropriate architectural layer.

Confidence score: 3/5

• This PR requires careful review due to significant changes in authentication flow and privacy consent handling
• Score reflects concerns about removing user consent mechanisms for telemetry collection, which may impact privacy compliance
• Pay close attention to middleware.ts, the database migration files, and the removed telemetry consent dialog functionality
