Subject: [PATCH] fix(agent): recognize node-launched Qwen Code on Windows
 (#33461)

Detect Qwen Code on Windows: exact node entrypoint identities for the npm (@qwen-code/qwen-code cli-entry/cli) and standalone (qwen-code/lib) layouts, and comparablePath now collapses . / .. segments so shim paths like .bin\..\ match.

Fixes #17326
Supersedes #17382
