Convert project to TypeScript with updated dependencies

[Copilot]

Converts entire codebase from JavaScript to TypeScript, updates all dependencies to latest versions, and configures proper type exports for library consumers.

Dependencies

• barcode-detector: 0.7.0 → 3.0.8 (API breaking changes handled)
• webrtc-adapter: 7.x → 9.0.3 (Edge now uses Chrome shim)
• Added TypeScript 5.6.3 with @typescript-eslint tooling

Type System

• Converted all src/misc/*.js → .ts with full type annotations
• Added typed interfaces: QRCodeResult, QRCodeLocation, KeepScanningOptions, CameraOptions
• Created type declarations for untyped dependencies (callforth, webrtc-adapter internals)
• All Vue components use <script lang="ts"> with typed props/methods

Build & Exports

• tsconfig.json configured for Vue 3 + strict mode
• Type definitions exported at dist/types/index.d.ts
• package.json updated with "types" field
• Postbuild script copies type definitions to dist

Example Usage

import { QrcodeStream, type QRCodeResult } from 'qrcode-reader-vue3';

// Full type inference and checking now available
const handleDecode = (result: QRCodeResult) => {
  if (result.content) {
    console.log(result.location.topLeftCorner); // typed as { x: number; y: number }
  }
};

Breaking Change: Library now requires TypeScript-aware build tools. Consumers get full type safety and IntelliSense support.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
