feat(api): export getWorld and healthCheck from workflow/api

[devyanshyadav]

Description

This PR resolves an inconsistency where the documented method for managing workflows (import { getWorld } from "workflow/api") was missing from the SDK's public exports, causing Module '"workflow/api"' has no exported member 'getWorld'.ts(2305) errors.

Key Changes

• SDK: Exported getWorld, healthCheck, and the World type from workflow/api and workflow/api-workflow.
• Documentation: Updated the getWorld API reference and the Postgres World deployment guides to use the correct unified import.
• Example Migration: Updated all workbench/ projects to follow the new standard, ensuring a consistent developer experience across the repository.
• Versioning: Included a changeset to trigger the appropriate package updates.

Verification

• Verified that getWorld and the World type are correctly resolvable and typed via the workflow/api entry point.
• Audited all workspace documentation to ensure synchronization with the code changes.

Missing exports for stepEntrypoint and workflowEntrypoint in workflow/api.ts causes build failures when base-builder.ts tries to import them

[pranaygp]

We actually need to fix up the examples and export some higher level "API" functions from 'workflow/api'

for now gonna fix the docs in #826 and then add some higher level exports to api

ideally you should seldom have to use getWorld unless you need explicit access to the world ( #621 will make things clearer)
