unclecode c046918bb4 Add memory-saving mode, browser recycling, and CDP leak fixes ...

- Add memory_saving_mode config: aggressive cache discard + V8 heap cap
  flags for high-volume crawling (1000+ pages)
- Add max_pages_before_recycle config: automatic browser process recycling
  after N pages to reclaim leaked memory (recommended 500-1000)
- Add default Chrome flags to disable unused features (OptimizationHints,
  MediaRouter, component updates, domain reliability)
- Fix CDP session leak: detach CDP session after viewport adjustment
- Fix session kill: only close context when refcount reaches 0, preventing
  use-after-close for shared contexts
- Add browser lifecycle and memory tests
