Add full application: receipt scanning, auth, billing, and account deletion
Brings the working codebase (Next.js app, auth system, Stripe billing, Docker/deploy config, tests, docs) into version control on top of the placeholder initial commit, and adds account self-deletion (Danger Zone in Settings, password + typed-email confirmation, cascading DB cleanup, Stripe cancellation) per GDPR right-to-erasure. Excludes local build caches, node_modules, and internal agent scratch files; .gitignore hardened to keep those out going forward. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
