refactor(test): add centralized TypeScript server factory for integration tests (#477)

# refactor(test): add centralized TypeScript server factory for
integration tests

  - Create TypeScriptServer class for managing TypeScript MCP servers
  - Add dedicated typescript/ directory with server infrastructure
  - Refactor TsTestBase to use TypeScriptServer for stdio transport
- Extract TypeScript test tools (greet, multi-greet, prompts, resources)
  - Use npx tsx for direct execution (better performance than npm run)
  - Install TypeScript dependencies automatically in test setup

  The TypeScriptServer factory provides:
  - startSse(port): Start SSE transport server
  - startStdio(): Start STDIO transport server
  - stop(): Graceful server shutdown
  - installDependencies(): npm install automation
