Summary

Restructure @workflow/web-shared to be a pure UI component library by moving server-side code to @workflow/web
Add world-actions/ module with shared world operation helpers that don't depend on Next.js server actions
Add runtime subpath exports to @workflow/core for direct module imports

Changes

@workflow/web-shared

Move all UI components into src/components/ subdirectory
Remove server actions and API client (moved to @workflow/web)
Remove server subpackage
Breaking: Components now accept callbacks as props (e.g., onSpanSelect, onWakeUpSleep, onResolveHook) instead of directly calling server actions

@workflow/web

Add src/server/workflow-server-actions.ts with all server actions
Add src/lib/workflow-api-client.ts for client-side API wrapper
Add src/lib/hooks/use-stream-reader.ts hook
Update components to use prop-based callbacks

@workflow/core

Add subpath exports: ./runtime/start, ./runtime/helpers, ./runtime/resume-hook
Add runs.ts module with shared helpers (recreateRunFromExisting, cancelRun, reenqueueRun, wakeUpRun)

Test plan

Local o11y

Verify trace viewer renders correctly
Test replay run functionality from web dashboard
Test cancel run functionality
Test wake up sleep functionality
Verify streams display correctly

Vercel o11y

Verify trace viewer renders correctly
Test replay run functionality from web dashboard
Test cancel run functionality
Test wake up sleep functionality
Verify streams display correctly

I think this should instead be:

<WorkflowTraceViewer worldApi={worldApi} />

and similar for streamers, etc.

Pull request overview

This PR refactors @workflow/web-shared to separate UI components from server-side code, creating a cleaner architecture where:

@workflow/web-shared becomes a pure UI component library with prop-based callbacks
@workflow/web contains all server actions and API client code
@workflow/core adds runtime subpath exports for direct module imports

Changes:

Moved server actions from web-shared to web
Converted components to accept callbacks as props instead of environment variables
Added world operation helpers to @workflow/core/runtime
Removed server subpackage from web-shared

packages/web/src/lib/workflow-api-client.ts:1040

The enabled option defaults to true but the loading state is initialized with this value directly. This means that when enabled is false, the component still briefly shows a loading state. Consider initializing loading state with false when enabled is false from the start.
packages/web-shared/src/components/sidebar/events-list.tsx:5
The import path includes .js extension in '../trace-viewer/types.js' while other imports don't use extensions. This inconsistency could cause issues with some TypeScript/bundler configurations. Consider removing the .js extension for consistency with other imports in the file.
packages/web/src/server/workflow-server-actions.ts:52
The function createVercelWorld is being redefined locally when @workflow/world-vercel already exports this function. This creates code duplication and maintenance burden. Consider importing and using the existing function from the package instead of reimplementing it.
