0.15.29: CSP bypass via CDP Runtime.evaluate for evaluate/snapshot/waitFor/initScript
- evaluateInTab/executeInTab now run through CDP Runtime.evaluate instead of
new Function() in MAIN world, so chrome_evaluate/chrome_snapshot work on pages
that block unsafe-eval (github.com, many bank/SaaS apps). Preserves value
markers (undefined/function/symbol/bigint/Error), DOMRect expansion, and the
expression/statement fallback; keeps {ok,value} error envelope.
- page.waitFor polls via service-worker-side CDP evaluation.
- chrome_navigate initScript uses Page.addScriptToEvaluateOnNewDocument.
- Add npm test (test-suite/unit/csp-eval.test.mjs) and in-browser regression
challenge 42 strict-csp-evaluate; update challenge 39 notes + docs/primer.

They work even on pages that block `'unsafe-eval'` (e.g. github.com and many bank/SaaS apps). `chrome_navigate`'s `initScript` injects at document_start via CDP and likewise bypasses CSP. `chrome_screenshot`, tab tools, and real Chrome input also keep working under any CSP. ## How do I tell whether a click or type worked? |
