Greptile Summary

This PR accomplishes two main objectives: removing 25 unused shadcn UI components to reduce bundle size and complexity, and refactoring the job queue system to add a new email verification feature with better organization.

Key Changes:

• Removed unused UI components (accordion, alert, calendar, carousel, chart, etc.) that were scaffolded but never utilized
• Restructured job definitions from src/lib/server/jobs/ to src/features/jobs/ following feature-based architecture
• Added comprehensive email verification job with proper type safety, Zod validation, retry logic, and configurable job options (exponential backoff, expiration)
• Updated all import paths to reference the new job registry location
• Minor comment cleanup in Nitro config

Quality Observations:

• All removed components had zero dependencies in the codebase
• Job refactoring is complete with no broken imports remaining
• New email job implementation includes proper error handling via Zod validation and sensible queue configuration
• Dependencies (email components and utilities) are correctly satisfied

Confidence Score: 5/5

• This PR is safe to merge with no critical issues identified. All removals are verified unused, refactoring is complete with correct import paths, and new functionality is properly implemented.
• Score of 5 reflects: (1) Complete and verified removal of unused components with zero broken dependencies, (2) Proper refactoring of job system with all import paths updated correctly, (3) Well-implemented email verification job with type safety, validation, and sensible configuration, (4) All required dependencies exist and are correctly referenced, (5) Clean architectural change from lib-based to feature-based organization following best practices.
• No files require special attention. All changes are straightforward removals or properly organized additions.

Important Files Changed

Filename	Overview
src/features/jobs/definitions/email.job.tsx	New email verification job implementation with proper type safety, error handling, and job configuration. Uses Zod for payload validation and includes sensible retry/expiration settings. Dependencies on email component and send utility are correctly satisfied.
src/features/jobs/register.ts	Clean aggregation file that registers all job definitions. Simple and correct implementation following the existing pattern.
src/lib/server/queue.ts	Updated import path from moved job registry file. Change is correct and consistent with the refactoring.
