Fix/stealth consistency

Browse Source 
hasIframeProxy fix contentWindow now returns null when parentNode === null (iframe never inserted into any tree). The previous attempt used isConnected, which broke getBehemothIframe by returning null for iframes inside the phantom iframe's detached document. That caused PHANTOM_DARKNESS to fall back to self (main window), making all DOM measurement ops run on the main document instead of the isolated iframe body, which corrupted the fingerprint element lookup.

Worker auto-execution Worker constructor now resolves relative URLs against location.href, fetches the script, and auto-runs it. The worker scope exposes WorkerGlobalScope so IS_WORKER_SCOPE resolves correctly in creepjs. All three worker types now complete within the 3s timeout instead of silently timing out.

AudioBuffer + AudioContext AudioBuffer class added to globalThis with getChannelData, copyFromChannel, copyToChannel. AudioContext.createBuffer returns a real instance. AudioContext.addEventListener was a no-op; startRendering now dispatches to stored listeners so the complete event fires.

Crypto Crypto class added to globalThis with randomUUID and getRandomValues on its prototype. Fixes ReferenceError in getPlatformEstimate.

NetworkInformation + ContentIndex NetworkInformation class with downlinkMax on the prototype clears noDownlinkMax. ContentIndex stub on globalThis clears noContentIndex. navigator.connection is now a real NetworkInformation instance.

getElementById / querySelector stale index fix id_index only registers nodes at creation time. When replaceChild(fragment, el) swapped in new nodes their IDs hit .or_insert() and were skipped, leaving the index pointing at the detached original. getElementById now verifies the indexed node is in the live document and falls back to a full attribute-selector scan. query_selector_from falls through to the full scan on both index miss and stale entry instead of returning None early.

matchMedia Handles common queries instead of always returning false. prefers-color-scheme: dark returns true (headless Chrome defaults to light mode, so returning true for light is a bot signal). any-pointer: fine, hover: hover, prefers-reduced-motion: no-preference, min/max-width, and (color) return sensible values.

Fingerprint consistency jsHeapSizeLimit raised to 4294705152 (4 GB, matching 64-bit Chrome). getHighEntropyValues platform corrected from "Linux" to "Windows", platformVersion from "6.1.0" to "10.0.0" to match the Windows NT 10.0 UA string. Canvas: real PNG encoder, arc fill, multiply blend mode. Screen class, performance.now, chrome runtime errors fixed.

Build note deviceMemory and hardwareConcurrency use the high-value pools ([4, 8] GB and [4, 6, 8, 12, 16] cores) only when built with --features stealth.
