fix(workflow): improve typing for state parameter

[Rootlogger]

Summary

Replace DangerouslyAllowAny with unknown in WorkflowState and WorkflowStepState types to provide stricter type checking for workflow state parameter in execute handlers.

Changes

• packages/core/src/workflow/internal/state.ts: Changed data: DangerouslyAllowAny to data: unknown
• packages/core/src/workflow/types.ts: Changed WorkflowState<INPUT, DangerouslyAllowAny> to WorkflowState<INPUT, unknown>

Motivation

This addresses issue #645 where state was typed as any making it difficult to debug workflow execution code. Using unknown provides better type safety while maintaining compatibility with existing code.

Testing

The change is purely TypeScript type-level and does not affect runtime behavior.

Closes #645
