Frequent JavaScript heap out of memory

Describe the bug

Every few minutes the copilot CLI crashes with the following output:

Affected version

GitHub Copilot CLI 1.0.83-5

Steps to reproduce the behavior

1. Initiate some work
2. Wait a few minutes

Expected behavior

don't crash.

Additional context

The CLI is executed on x86_64 Ubuntu/Linux 24.04, fully updated
It is access like Windows Terminal-->ssh-->Linux-->tmux/zsh-->CopilotCLI (no difference when running directly on the linux machine)

Have tried to use NODE_OPTIONS but it is silently ignored.

Reproduce the crash by initiating work in Copilot CLI 1.0.83-5 on Ubuntu/Linux 24.04 and waiting several minutes. Start with the generated Node.js report file and the CLI's handling of NODE_OPTIONS; done means the same workload no longer ends in a JavaScript heap out-of-memory crash.
