Smart WebView 8.0.1 (Polish & Stability Patch)

Following the major v8.0.0 release, this patch addresses a critical crash on startup and finalizes the documentation and code cleanup to ensure the "Legacy" edition is robust and accurate.

🐞 Critical Fixes

• Fixed QR Scanner Crash: Resolved a Fatal Exception caused by the QRScannerPlugin attempting to register lifecycle callbacks too late during app startup.
• Modernized Camera API: Migrated the QR Scanner implementation from the deprecated IntentIntegrator to the modern AndroidX ScanContract, ensuring better compatibility with newer Android versions.

📚 Documentation & Cleanup

• Docs Overhaul: Updated all documentation files to correctly reference swv.properties as the single source of truth for configuration, removing obsolete references to SmartWebView.java.
• Code Cleanup: Filtered and removed legacy comments, old labels, and redundant code to leave the codebase clean for future maintainers.
• UI Polish: Removed residual "Premium" labeling and upsell links from the Playground and Demo pages to reflect the fully open-source nature of the project.
