ci: add centralized E2E workflow

[casey-brooks]

Summary

• Add the centralized E2E workflow for Threads using agynio/bootstrap/.github/actions/provision@main, devspace dev, and agynio/e2e/.github/actions/run-tests@main.
• Remove the local in-repo E2E runner/test pod wiring and stale test/e2e tests now owned by agynio/e2e.
• Add a restore-argocd DevSpace pipeline for workflow cleanup.

Architecture checks

• No PR image builds or chart package/push steps were added.
• No cluster environment overrides were added to the E2E workflow.
• No pinned action refs or pinned E2E refs were added; reusable actions use @main.

Update

Fixed the DevSpace deployment patch target to match the bootstrap release (deployment/threads).

Update

Adjusted the default DevSpace flow so CI starts the dev session in the background, performs the readiness check, then stops the session. This keeps devspace dev usable for the non-watch CI deploy-from-source step.

• actionlint .github/workflows/*.yml — passed with no errors

Update

Fixed the readiness probe command to use kubectl exec ... sh -c against deployment/threads, avoiding the missing bash binary in the original bootstrap image while the dev image rolls out.
