Task 02: Workflow event contracts

Acceptance

• Workflow step API responses preserve on_children_completed and other existing generic trigger fields instead of dropping them.
• Frontend workflow event types accept on_children_completed generic actions.
• E2E API helpers can configure on_children_completed without type escapes.

Verification

go test ./internal/task/dto/...
cd apps && pnpm --filter @kandev/web typecheck

Files Likely Touched

• Existing frontend type file: apps/web/lib/types/workflow-actions.ts.

Output Contract

When finished, update this task frontmatter to status: done, update the checkbox in plan.md, and report:
