feat: log intermediate hops for NTLM auth in timeline

[prateek-bruno]

Description

Internal - BRU-4384
Fixes #6788

Intermediate NTLM request hops are not recorded in the timeline, any developer who wants to inspect it can't. The fix is to capture the intermediate hops from the ntlm adapter and correctly log them in the timeline.

Problem

Intermediate NTLM request hops are not recorded in the timeline, any developer who wants to inspect it can't.

This is because of our adapter design where the Bruno's timeline interceptor isn't able to reach the requests running inside the NtlmClient cause it is an adapter and only provides and runs on final response.

Fix

The fix is to capture the intermediate hops from the ntlm adapter and correctly log them in the timeline.

We track the requests and then construct the timeline rows for those requests and insert it.

NOTE:

• We construct a timeline info per request which looks identical to our bruno interceptor's timeline's info
• All requests rows are fetched except the last one cause Bruno's interceptor captures it (if it has response)
• Since Bruno's interceptor will already add a request opening block in Timeline, we insert the rows before the last separator so that the rows for hops are visible correctly before the final result (also handles redirect)
• The final entry in timeline will still display the total response took time instead of just for that one hop

Summary by CodeRabbit

• New Features

  • NTLM authentication handshake requests are now shown in the request timeline.
  • Timeline entries include request details, response information, and headers where available.
  • Failed or refused NTLM handshakes are also recorded for improved visibility.

• Bug Fixes

  • Improved request history accuracy for authentication flows that bypass standard request interceptors.

Walkthrough

The NTLM adapter now records all internal handshake requests and adds formatted request, response, header, data, and timing rows to the request timeline. Tests cover successful and refused handshakes.

Changes

NTLM timeline logging

Layer / File(s)	Summary
Reusable timeline formatting packages/bruno-electron/src/ipc/network/network-log.js, packages/bruno-electron/src/ipc/network/index.js	Shared helpers create timestamped timeline rows for requests, responses, headers, data, separators, and information messages.
NTLM capture and validation packages/bruno-electron/src/ipc/network/index.js, tests/auth/ntlm/ntlm.spec.ts	The adapter records all NTLM handshake requests, adds them to successful and error timelines, and verifies authorization header behavior and refused handshakes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 37451

The change improves NTLM timeline visibility, but a network-failed handshake leg can still be missing when no response is available, limiting diagnosis of some failures. The PR is mergeable with owner awareness and follow-up to preserve these failed hops.

Poem

Three handshake steps now leave a trace,
Headers appear in their proper place.
Success or refusal, rows remain,
The timeline records each exchange again.
NTLM travels with logs in pace.
