What and why?

Groups the serverless-owned e2e tests and their helpers under e2e/serverless/, with one subdirectory per feature (lambda, cloud-run, container-app, aas). These cloud-instrumentation tests and their verifiers were sitting flat among the other e2e files, and their ownership was spelled out across ~9 CODEOWNERS lines and duplicated path lists in CI.

Collecting them by package gives a single ownership boundary -- mirroring how packages/base/src/helpers/serverless already gets one CODEOWNERS entry -- and lets each CI change-detection filter point at a package glob instead of enumerating individual files. Adding a test, verifier, or shared helper no longer requires editing ci.yml. Non-serverless tests (junit, sarif, sbom, sourcemaps, synthetics, git-metadata, version) stay flat at the top level.

How?

• Moved each feature's *.test.ts and its verifier into e2e/serverless/<feature>/:
  • lambda/ -- lambda.test.ts, lambda-verifier.ts
  • cloud-run/ -- cloud-run.test.ts, cloud-run-verifier.ts
  • container-app/ -- container-app.test.ts, container-app-verifier.ts
  • aas/ -- aas-linux.test.ts, aas-windows.test.ts, aas-verifier.ts
• Kept the cross-cutting helpers (`telemetry-checker.ts`, `traffic.ts`) in `e2e/serverless/helpers/`. `exec.ts` and `junit-upload-checker.ts` stay in `e2e/helpers/` since they're shared / non-serverless.
• Rewrote the relative imports affected by the moves: tests reach the shared `exec` at `../../helpers/exec`, their sibling verifier at `./-verifier`, and shared helpers at `../helpers/...`; verifiers reach `exec` at `../../helpers/exec`.
• Removed `e2e/helpers/cloud-run-telemetry-checker.ts`, a thin wrapper that adapted a `string` arg to `checkTelemetryFlowing({serviceName})`. `cloud-run.test.ts` now imports `telemetry-checker` directly and uses the same call signature as the other tests.
• Collapsed the serverless e2e CODEOWNERS block into a single `e2e/serverless/` entry and dropped two stale `e2e/fixtures/*` lines (those dirs don't exist).
• Repointed each CI change-detection filter at `e2e/serverless//` plus `e2e/serverless/helpers/`.

No Jest or tsconfig changes needed: e2e discovery is recursive (`roots: ['e2e']`) and `e2e/tsconfig.json` already covers the new subdirs.

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
