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>

* Empirical Challenger 1 (Deep Adversarial Stress Suite) — Milestone 4 (R4)

*

* Comprehensive Stress Testing of:
|

* 1. Responsive Shell & Drawer Transitions (rapid open/close, toggle cycles, body scroll lock invariants)
|

* 2. ESC Key Dismiss & Route Transition Cleanup
|
||||
* 3. KPI Engine Extreme Value Testing (0 receipts, 10,000 receipts, all-unconfirmed, all-flagged, negative amounts)
|

* 4. Multi-tax and zero-tax edge cases, float stability, and accuracy tier bounds
