Pull request overview
Adds network inspection and export capabilities to the agent-browser CLI/protocol so users can capture API flows (requests + responses) during a browsing session, including new “network response” and “network dump” commands and enhanced request filtering/redaction.
Changes:
- Extend request tracking to include monotonically increasing request IDs plus response status/headers, with multi-page listener attachment.
- Add new protocol/types for
networkdumpand extendrequestscommand options (host,type,redact). - Update CLI parsing to support
network responseandnetwork dump, plus newnetwork requestsfilters.

- Use Map<number, TrackedRequest> for O(1) response matching instead of find() - Add networkdump and responsebody to ACTION_CATEGORIES under network - Include response headers in responsebody action output
