Description

Resolves #677

This PR implements hands-free speech recognition control inside ReGenX using the Web Speech API (window.SpeechRecognition / window.webkitSpeechRecognition). Cues and action confirmations are spoken back using window.speechSynthesis.

What changed

• Added Speech recognition object inside Intelligence in src/intelligence.js.
• Implemented voice commands:
  • "Scan Waste" or "Open Scanner" -> Opens the BioScan AI scanner.
  • "Confirm Weight [number]" -> Sets the weight in the confirmation modal and clicks the confirm button.
  • "Submit Dispatch" -> Submits the provider's dispatch request.
  • Navigation commands: "Sustainability Hub", "Compliance Center", "Dashboard Overview".
• Wired Speech Recognition initialization to executeLogin and shutdown to doLogout inside src/app.js.

Why

A hands-free interface allows riders and plant workers to interact with the PWA without needing to touch their device screen while handling waste.

How to test

1. Log in to the application.
2. Grant microphone permissions when prompted.
3. Say: "Open Scanner" to open the BioScan AI view.
4. Try saying "Sustainability Hub" to navigate.
