test: stabilize target worker e2e

[chenjiahan]

Summary

This PR fixes a Windows CI flaky failure in the target e2e test. The test asserted console snapshots right after networkidle0, but worker postMessage logs can arrive slightly later, so the snapshot sometimes missed both Worker said messages. It now polls for the worker messages before snapshotting and keeps the final console snapshot order stable.

📝 Walkthrough

Walkthrough

The e2e target test file gains a workerConsoleMessages array listing expected worker console strings and a waitForWorkerConsoleMessages async helper that polls the collected consoleMessages array until entries prefixed with Worker said: match the expected ordered sequence. The sortByTerm comparator is updated to use includes(). Two existing multi-compiler webworker test cases (web + webworker default and with devServer: false) now await this helper after page navigation before asserting console message and page error snapshots.
