<issue_title>[Phase 5] Epic: Advanced Reliability</issue_title>
<issue_description>## Priority: P3
Phase: 3
Type: Epic

Overview

Epic Goal: Transform StormCom into a multi-vendor marketplace platform enabling independent sellers to list products, manage inventory, and fulfill orders while the platform owner collects commission fees and provides shared infrastructure.

This epic targets:

• Marketplace Owners: Launch Amazon/Etsy-style platforms with 100+ vendors
• Vendor Sellers: Access built-in customer base without marketing costs
• Platform Revenue: 10-20% commission on every sale ($1M GMV = $100K-$200K revenue)
• Competitive Positioning: Compete with Sharetribe, Arcadier, CS-Cart

Business Value

• Recurring Revenue: 10-20% commission on all vendor sales
• Network Effects: More vendors → more products → more customers → more vendors
• Lower CAC: Vendors bring their own customers to platform
• Scalability: Onboard 100+ vendors without proportional support costs
• Enterprise Market: B2B marketplaces (wholesale, industrial supplies)
