fix(cli): add timeout and progress output to npm install during update (supersedes #24391, #18866)

[shellybotmoyer]

This PR supersedes #24391 and the original #18866.

It applies the same fix (add timeout=300 to npm install during hermes update, switch from --silent to --loglevel=warn, and add _relay() progress output for build failures) on top of the latest origin/main.

What changed

• Rebased onto current origin/main to resolve the merge conflict in hermes_cli/main.py
• The _relay() helper from the earlier merge is preserved alongside the timeout/loglevel changes from fix(cli): add timeout and progress output to npm install during update (supersedes #18866) #24391

Closes #18866
Supersedes #24391

[shellybotmoyer]

Superseded by upstream commit c844d15 which merged a better fix for #18840 (stream npm install output with capture_output=False instead of --silent). This PR branch is now 149 commits behind main and has merge conflicts in hermes_cli/main.py. Closing in favor of the upstream solution.
