⚠️ Do not merge — diagnostic experiment only

This branch is the last-known-good commit (b76bf7288, Jun 29 11:35, immediately before #3961) plus a single CI-only change: the E2E job timeout is capped at 45 min so a hang fails fast instead of blocking the Windows queue for 3h.

The diff looks like it reverts everything since June 29 — that is expected. The whole point is to run old product code on today's CI. Nothing here is meant to land on trunk.

Why

To separate a code regression from an environment change as the cause of the Windows E2E 3-hour hangs (AINFRA-2588). This commit was in the healthy ~21-min era.

How to read the E2E Tests on windows-x64 job

  • Passes (~21 min) → environment is fine today; the hang is a code regression introduced after this commit.
  • Hangs / killed at 45 min → the environment changed since June 29 (AMI / infra / external dep); old code that passed then fails now.

Ignore the linux E2E step (mid-development at this commit) and the aggregate "E2E Tests" GitHub status (last-write-wins across platforms) — read the windows-x64 job directly.

Only .buildkite/pipeline.yml differs from b76bf7288 (the 45-min cap).

🤖 Generated with Claude Code

Runs the last-known-good commit (b76bf72, just before #3961) on today's
Windows CI to separate a code regression from an environment change. Only
the CI job timeout is changed; product code is untouched.
