Add a native Instagram login flow that uses one session for messages and push notifications. The flow is available for both cloud and on-device connections.

  • Sign in once, including verification, and use that session for messaging and push registration.
  • Register native push through Beeper's existing relay so Instagram can wake an on-device connection while Beeper is in the background.
  • Save the session and push keys so reconnecting and renewing registration don't require another login.
  • Reuse the existing message processing and sync handling. Keep existing web sessions working.
  • Use req/uTLS for the native TLS and HTTP/2 profile, and the official FlatBuffers library for stream requests and responses.

Validation includes a fresh Android login, self-hosted login and restart, sending and receiving with native sessions, and background notifications on Android and iOS. Fresh iOS setup remains unverified because the SMS never arrived. A fresh install of Instagram's own Android app reproduced that nondelivery too.

Rollout requires enabling instagram-native for the cloud and local login flows.

@highesttt can you test this out as well please? Isn’t this the login flow that wasn’t giving cookies that worked with the rest of the bridge (mobile only cookies or something)?

Select the captured TLS profile from native login state, use the normal gateway for native streams, and restore the shared login request retries.

Was this something actually missing from the web login code, or was it just for the mixed native+web login thing that was removed? (also are there any other leftovers of that mixed login flow?)

  1. Was the SMS request missing from web login? Any mixed-login leftovers?

It was missing from web login too. I found it during the mixed-flow work, but Instagram’s website makes a separate request to send the first SMS. We were showing the code field without making that request, so that fix stays.

There were leftovers I should have removed. Those are gone now.

  1. What were the manual FlatBuffers checks for?

I kept them after switching to the generated decoder and missed that the surrounding DGW handler already catches decoding failures and reconnects. I removed the whole wrapper. It now uses the generated decoder directly.

  1. Keep the source-version comment.

Agreed and done.

I renamed the new login flow to android since instagram-native will be even more confusing if we ever add ios (and there's no need for the instagram- prefix anymore with IG and FB fully split up)

Everything mostly looks good now, but @highesttt should also review the login parts

Looks reasonable, tested on multiple accounts from different countries, works well
