feat: per-source browser instance isolation

- nh_cdp_port: stable per-source CDP port (9300+name hash)
- nh_entry_write: entry scripts now export CDP_PORT_OVERRIDE +
  CDP_PROFILE_OVERRIDE so parallel harvests each drive a dedicated
  Chromium (own port + own profile); regenerated idempotently
- pairs with news-hub-skills CDP_PROFILE_OVERRIDE support
- darwin test asserts isolation env in generated entry
