refactor: hoist all devDeps to root

[overbalance]

What this does

Hoists all build devDependencies to the root package.json.

• 14 fewer packages in node_modules (1.13% reduction)
• 878 fewer in dependency tree (11.39% reduction)
• 304 fewer packages added by npm ci (10.44% reduction)

Key changes

Test fixes

• Updated karma configs to load plugins from root after dependency hoisting
• Fixed webpack process polyfill path for ESM compatibility
• Updated expect import syntax for socket.io tests
• Updated AWS SDK mock response Content-Length headers

Dependencies

• All build devDependencies moved to root package.json
• Removed unused jQuery dependencies

Configuration

• Converted root .mocharc.yml to .mocharc.json
• Fixed axios import syntax in express example (namespace import → default import)

Package-specific changes

@opentelemetry/instrumentation-socket.io

• Changed import * as expect to import expect (expect v29 uses default export)

@opentelemetry/instrumentation-dns

• Added @ts-expect-error annotations for shimmer __wrapped properties

@opentelemetry/instrumentation-aws-sdk

• Updated Bedrock mock response Content-Length headers

Browser packages (propagator-aws-xray, propagator-instana, instrumentation-user-interaction, instrumentation-long-task)

• Updated karma.conf.js to load plugins from root package.json

@trentm If Node 18 support is needed then there's more work to do. I missed this requirement when I started this work. 😕 How do you want to proceed? Try to roll back dependency versions until it's happy?

npm warn EBADENGINE   package: '@azure-rest/[email protected]',

🤔 We say we support Active and Maintenance LTS versions of Node, and Node 18 is officially end of life. So it might be fine in Contrib to drop support for 18. That's a bigger discussion though (cc @open-telemetry/javascript-maintainers ) and we'll need to update docs too.

@overbalance I don't think those EBADENGINE warnings are blocking for this PR. We already have a number of those warnings in the current state. Unfortunately an EBADENGINE warning will matter for some deps, but not for some deps that are just for testing. For example this one:

npm warn EBADENGINE Unsupported engine {
npm warn EBADENGINE   package: '@azure/[email protected]',
npm warn EBADENGINE   required: { node: '>=20.0.0' },
npm warn EBADENGINE   current: { node: 'v18.20.8', npm: '10.8.2' }
npm warn EBADENGINE }

That dep is used by tedious@17:

% npm ls @azure/core-auth
[email protected] /Users/trentm/src/opentelemetry-js-contrib
└─┬ @opentelemetry/[email protected] -> ./packages/instrumentation-tedious
  └─┬ [email protected]
    ├─┬ @azure/[email protected]
    │ ├── @azure/[email protected]
    │ ├─┬ @azure/[email protected]
    │ │ └── @azure/[email protected] deduped
    │ └─┬ @azure/[email protected]
    │   └── @azure/[email protected] deduped
    └─┬ @azure/[email protected]
      ├─┬ @azure-rest/[email protected]
      │ └── @azure/[email protected] deduped
      ├── @azure/[email protected] deduped
      └─┬ @azure/[email protected]
        └── @azure/[email protected] deduped

which is a test dep. We intentionally install a recent-ish major version of tedious so that unit tests (i.e. npm test) for an instrumentation (instrumentation-tedious in this case) tests with a relatively modern version of the target package. We then rely on our test-all-versions tests to handle testing against those versions of tedious that work with older Node.js versions (e.g. Node.js v18)

@trentm Those warnings are blocking CI from what I see. What do you recommend?

Those warnings are blocking CI from what I see.

I don't know what is going on. I can npm ci this feature branch locally.

This CI step failed with a network error: https://github.com/open-telemetry/opentelemetry-js-contrib/actions/runs/18537223726/job/53057847496?pr=3032

The other test jobs are stuck in npm ci. I cancelled the run after 20m.
I think the "network aborted" above is just a fluke. The real issue is the stuck npm ci steps.

The lint workflow, which does npm ci --ignore-scripts, worked fine.

Ideas on what this could be:

• Some install/build/postinstall script in one of the deps is breaking things.
• Some GitHub Actions or npmjs bug/incident that is causing this to break.
• Some limit is being hit in GH Actions? THis is total guess.

@trentm I repaired the lockfile and this is finally 🟢. Thanks for your help.
