Reason for change: support for network connection
Test Procedure: build should be successful.
Risks: low
Priority: P2

🟡 Changes recommended

A critical connection-lifetime race can cause use-after-free during WebSocket sends, while additional findings identify broken metric capture and logging, inaccurate HAR timing, and incorrect transfer-size reporting.

What changed in this PR

Adds network-request inspection to the RDK NativeScript debugger, streaming native download metrics to a new Network tab with HAR export.

Changes:

• Adds live request summaries, bounded capture history, and HAR downloads.
• Replaces stored native metrics with capture-controlled streaming.
• Adds shared WebSocket send helpers and connection locking.
