Generate TypeScript definitions for safe outputs JSONL types

[Copilot]

This PR addresses the need for TypeScript definitions covering the safe outputs system by providing type definitions for JSONL output items produced by agents.

What was implemented

TypeScript Definitions (pkg/workflow/js/types/safe-outputs.d.ts)

The new TypeScript definitions file provides type safety for:

JSONL Item Types: Complete interfaces for all safe output items with proper validation:

• Union type SafeOutputItem covering all possible output types
• Individual item interfaces like CreateIssueItem, CreatePullRequestItem, etc.
• Proper type discrimination based on the type field
• Base interface BaseSafeOutputItem for common properties

Validation

• ✅ TypeScript compiler validation (zero errors)
• ✅ All existing tests continue to pass
• ✅ Linting and formatting applied
• ✅ Cross-referenced with Go structs and JavaScript validation logic
• ✅ Manual testing of CLI functionality

Impact

This provides type safety for developers working with the safe outputs JSONL system, ensuring consistency between TypeScript usage and the actual Go/JavaScript implementation. The definitions accurately reflect the real behavior rather than just the documentation.
