SGavrl 1a1253118f feat(cli): default V8 heap to 4 GB on 64-bit so heavy SPAs don't OOM (#199) (#202)
V8 embedded defaults to ~1.4 GB max-old-space on 64-bit. Pages with
  heavy fingerprinting or analytics bundles (e.g. demo.fingerprint.com/
  web-scraping) blow past it and the worker dies with
  'Fatal JavaScript out of memory' and SIGTRAP, taking the CDP session
  with it.

  Always set --max-old-space-size=4096 (1024 on 32-bit targets) before
  V8 startup, matching headless Chrome's default. User-supplied
  --v8-flags are appended after the default so they win (V8 parses
  left-to-right and the last value wins), which keeps the existing
  escape hatch intact for memory-constrained environments.
