…k to opening about:blank (#1749) # why Stagehand API failures were caused on all routes `/act`, `/observe`, etc. when session init failed because a page was closed. This adds a fallback to open about:blank so at least the session remains usable instead of just crashing on init. # what changed # test plan <!-- This is an auto-generated description by cubic. --> --- ## Summary by cubic Fixes session init when connecting to a browser with zero pages by auto-creating an about:blank tab. Keeps Stagehand routes working after the last page closes and surfaces lint failures via a dedicated cancellation job. Addresses STG-1450. - **Bug Fixes** - Replace waitForFirstTopLevelPage with ensureFirstTopLevelPage: check for an existing page, wait with timeout, then create about:blank if none. - Simplify errors to a TimeoutError with clearer context; improve logging and add an integration test for zero-page init. - **CI** - Run cancellation in a separate job only when lint fails, so failures are visible instead of marked skipped. <sup>Written for commit 45ed6dc.
