Mac connections can stop updating while the viewer remains responsive and TCP stays connected. This change adds a visible incoming traffic meter and opt-in connection-progress diagnostics to distinguish missing data, unfinished updates, pending requests, and socket event dispatch problems.

• Expose the existing traffic graph through a saved viewer option and -ShowStats; include buffered incoming data and avoid rate-calculation overflow.
• Add -ConnectionDiagnostics with monotonic timing, update progress, socket readiness, callback counts, and slow-processing records.
• Provide a Windows launcher that retains session logs and process/connection samples, including support for stock 1.16.0's fixed log path.
• Package a portable Windows viewer and run the real viewer against idle, paused, and resumed RFB updates in CI.

Validation: the viewer builds on Linux and Windows. The integration replay passes on Linux and on pf-omen using the packaged Windows executable, including pending-request and socket-readiness assertions. The user reports the latest deployed version is working well.

The original freeze's cause remains unconfirmed. Diagnostics are disabled by default, and the meter measures incoming socket payload rather than outgoing traffic or TCP/IP overhead.
