Initial commit: Voiced invoice desktop app

Offline-first invoicing app for Arun P, built by Bongbetic. - Tauri v2 (Rust) + React/TypeScript + IBM Carbon Design System UI - SQLite (rusqlite) storage with a persistent invoice-number series - Guided first-run setup, pre-filled vendor/bank details - Fixed-amount or rate x quantity line items (per sec/min/hour/session/unit) - GST as CGST+SGST or IGST, Indian amount-in-words - Optional signature, with a computer-generated note as fallback - Print-ready PDF export via @react-pdf/renderer - Windows cross-compile via cargo-xwin (NSIS installer) Co-authored-by: CommandCodeBot <noreply@commandcode.ai>
