v461 — the Browser drill opens a window you can actually watch

The Browser drill opens a window you can actually watch

browser_open now shows a visible Chrome/Edge window by default; "headless":true is the opt-in exception. The Browser drill's step 3 refuses a headless result and tells the model to retry with "headless":false; the Browser screen's checkbox follows the running mode, and switching to visible restarts a headless instance cleanly.

window_open now brings the named program to the front, and window_type reads the window back through Windows UI Automation so its result says whether the text actually landed. The Frontier drill requires that read-back, and the live strip names the call to retry when it is unverified.

Verified live with NEMOTRON-3-ULTRA: Browser 9/9, one clean pass, zero failed attempts, in an unobstructed Edge window. The earlier headless run was not counted.

The head-to-head teaser is in the README and the Pages site.
