Give the gate build job room and stop a stalled friend-module build from eating it

[Ewerton Scaboro da Silva (ewertons)]

Failure

build_linux_amd64 in the C gate is cancelled by the default 60 minute job timeout:

The job running on agent Azure Pipelines 17 ran longer than the maximum time of 60 minutes.

No step reports an error of its own. The change under test is unrelated to it.

Cause

The job's cost is high and variable. Three recent runs of the same gate, same steps, same agent image:

job total	checkout	language image	friend module
41m	17m15s	4m39s	18m06s
54m	15m14s	4m39s	33m02s
60m (cancelled)	15m20s	4m34s	killed at 39m05s

A healthy run already spends 41-54 of its 60 minutes, and the friend-module step alone varies by more than 15 minutes between runs that differ in nothing. There is no headroom, so a run at the slow end of the normal range is cancelled.

Inside that step, the lerna bootstrap --hoist layer installs ~640 packages and prints nothing while it does so. It was silent for 7m47s in a run that passed, and for 26m35s in the run that was killed, still silent at the end. Agent CPU was 0.5-1% throughout and disk was not exhausted.

Fix

• timeoutInMinutes: 120 on build_linux_amd64 in all five gate templates. They share the same step template and the same near-cap cost.
• Bound the friend-module docker build at 40 minutes and retry it once. 40 minutes clears the slowest healthy run seen (33m) and fits the budget twice: ~22 minutes of checkout and language image plus two attempts and the push stays inside the 120 minute cap. The retry is cheap because layers completed by the first attempt are still in the local image cache, so the second attempt resumes at the layer that stalled. BUILD_TIMEOUT_SECONDS overrides the bound.

Raising the job timeout alone would very likely have carried the cancelled run. Bounding the build is what turns a future stall into a reported stall instead of an unexplained job cancellation.

Validation

Local. All five templates parse. The step script was extracted from the template, passes bash -n, and was exercised against a stubbed docker and the real timeout binary:

scenario	exit	build attempts	pushes
succeeds first time	0	1	1
build fails	1	2	0
build stalls	1	2	0
stalls, then succeeds	0	2	1

Both failure paths name the reason (Build made no progress within Ns and was stopped. / Build failed with exit code N.). The happy path is unchanged and adds no latency.

The docker build and ACR push themselves need a hosted agent and cannot be reproduced outside one.

Pull request overview

This PR adjusts Azure Pipelines gate jobs to avoid unexplained cancellations by (1) increasing job-level timeouts to provide headroom and (2) bounding the friend-module Docker build with a timeout + retry so stalls fail fast with an explicit error.

Changes:

• Increase build_linux_amd64 job timeout to 120 minutes across all gate job templates.
• Wrap the friend-module docker build in a timeout and retry it once to convert silent stalls into actionable failures.

Fresh occurrence of the failure mode this PR bounds: c gate build 162681 lost build and push default-friend-module to npm error network read ECONNRESET (lerna bootstrap, exit 152) after ~355s. A plain re-run passed, which is exactly the retry this PR automates.
