fix: disable WSL Windows Terminal progress

[ktwu01]

Related Issue

Fixes #727

Problem

Windows Terminal under WSL receives OSC 9;4 progress updates as Windows taskbar progress. While Kimi Code is responding, that progress state can prevent an auto-hidden Windows taskbar from revealing normally.

What changed

• Treat Windows Terminal sessions under WSL as unsupported for terminal progress reporting, while keeping native Windows Terminal and the existing allow-listed terminals enabled.
• Added regression coverage for common WSL environment signals with WT_SESSION.
• Added a patch changeset for the CLI fix.
