Update to Theia 1.66.x and switch to vscode-trace-extension

[jfaltermeier]

New build jobs:

• https://ci.eclipse.org/theia/job/cdt-cloud-blueprint-release/
• https://ci.eclipse.org/theia/job/cdt-cloud-blueprint-sign-notarize/
• https://ci.eclipse.org/theia/job/cdt-cloud-blueprint-upload/

What it does

• Update Blueprint version to 1.66.200, align all packages to Theia 1.66.2
• Upgrade Electron to 38.4.0, electron-builder to 26.0.12, electron-updater to 6.6.2
• Require Node.js >=20, update CI to Node.js 22.x and Python 3.13
• Replace legacy Jenkins release pipeline with split preview build, sign, upload jobs
  • See URLs above
• Updated bundled VS Code extensions and native dependencies

theia-traceviewer replacement

• Replace theia-traceviewer with the eclipse-cdt.vscode-trace-extension VS Code plugin. This requires adding some features of the theia extension to this workspace:
  • Add the @eclipse-cdt-cloud/trace-server-manager extension, providing commands to start, stop and restart the bundled Trace Compass server
  • Add the @eclipse-cdt-cloud/trace-server-proxy extension, which proxies trace server traffic through the Theia backend at /trace-server-proxy
    • The proxy auto configures the trace viewer preferences when THEIACLOUD_SESSION_URL env variable is set, as this is our typical cloud use case
    • If this environment variable is missing, the proxy is not active
    • This extension is only added in the non Electron applications

@jfaltermeier Thanks for your work. Regarding the proxy feature, do you have a guide on how to test it locally?

[jfaltermeier]

I think the easiest way would be via docker. Only expose port 3000.

This should reproduce the problem: docker run -it -p 0.0.0.0:3000:3000 cdt-cloud-blueprint:latest

This should work, because the proxy gets enabled: docker run -it -p 0.0.0.0:3000:3000 -e THEIACLOUD_SESSION_URL=http://localhost:3000/ cdt-cloud-blueprint:latest

Thank you! All features work (as they did before) and I like the Trace Server integration. With your manual I was also able to run it within docker.

There is one regression I noticed: When I start the Electron application I am stuck in the splash screen for 30 seconds until the main window shows up. My guess is that the window should already be ready but somehow the messaging/events are broken to show it. So we wait for the 30 seconds timeout for it to be shown. Can you reproduce the issue?

[jfaltermeier]

From what I can see, when I use yarn electron start --ozone-platform=x11 it works on Wayland. With just yarn electron start, it is much slower and the splash screen hangs around longer.

On X11 it also works.

This fix was added with 1.67, eclipse-theia/theia#16658, so this is not included here. Maybe this missing fix could cause a slowdown instead of a crash as well?

Hmm not sure, I will approve for now but we should create an issue and revisit with the next release

I've opened #104

I've retriggered the verification jobs, because they produce inputs for the mac builds I still need to download. I will merge the PR once they complete.
