LINUS ROUND 1: Delete dead code (rust/c), generic Store[T], tests, slim main.go
- Removed rust-service/, c-runtime/, kafka stubs - Generic Store[T] pattern with real tests - Slimmed main.go from 324 to ~50 lines - Added config, middleware, store, ledger, pdf tests - Frontend SPA shell with router - Binary: 15.5MB -> 12MB
