Subject: [PATCH] fix: Resolve all dart analyze errors and warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixed the following issues reported by dart analyze:

🔴 Errors Fixed:
- babel_binance_base.dart: Removed dispose() calls for TestnetSpot and TestnetFuturesUsd classes (they don't have dispose methods)

⚠️ Warnings Fixed:
- binance_base.dart: Removed unused import 'dart:io'
- rate_limiter.dart: Removed unused field '_orderCountResetTime'
- token_bucket.dart: Removed unused extension 'clamp' on double
- websocket_stream.dart: Added getter for '_lastPongReceived' to expose connection health monitoring

Changes:
- Removed 2 dispose() calls that were causing errors
- Cleaned up unused imports and declarations
- Added useful getter lastPongTime for WebSocket health monitoring
- All code now passes dart analyze without errors

No functionality changes - only code quality improvements.
