add logger to typescript package

[xzrderek]

Note

Adds Winston-based Fireworks logging with Vercel integration, introduces TS status/exception/types modules with re-exports, and updates build config to emit dist; also tweaks exception typing and a test filename/assertion.

• TypeScript package:
  • Logging: Add logging/fireworks-transport.ts (Winston transport to Fireworks), logging/logger.ts (configured logger, createRolloutLogger), and logging/fireworks-vercel.ts (Vercel withFireworksLogging).
  • Models: Add models/status.ts, models/exceptions.ts (OpenAI error mapping, retry helper), and models/types.ts (zod schemas/types). Replace prior inline schemas by re-exporting from index.ts.
  • Build/Config: Update package.json to output dist (main/types/exports, files, deps, version), and tsconfig.json to emit declarations to dist.
• Quickstart server (TS):
  • Refine exception map typing; call exception constructors without status code in exceptionForStatusCode.
• Tests:
  • Adjust non-test-prefixed discovery test to use unique filename and assert accordingly.
