…miting, and configuration - Added Client struct to manage WebSocket connections, including read/write pumps and rate limiting. - Implemented Hub struct to coordinate client registration, message broadcasting, and connection cleanup. - Created configuration management for server settings, including rate limiting and allowed origins. - Developed HTTP handlers for WebSocket upgrades, health checks, and a test page for client interaction. - Introduced rate limiter to control message sending rates per client connection. - Established origin validation to enforce access control for WebSocket connections. - Set up routing for application endpoints using an HTTP ServeMux. - Defined shared message types for communication between clients and the hub.
- Introduced BUILD_GUIDE.md for quick build commands and platform-specific instructions. - Created CROSS_PLATFORM.md detailing prerequisites, building, cross-compilation, and platform-specific code. - Developed CROSS_PLATFORM_GUIDE.md to provide an extensive guide on development setup, building, and troubleshooting across platforms. - Added CROSS_PLATFORM_SETUP.md summarizing cross-platform capabilities and configurations. - Compiled QUICK_REFERENCE.md for a concise reference on build commands, development workflow, and troubleshooting.
…logging, and message processing
- Added graceful shutdown mechanism in the Hub and HTTP server. - Implemented context-based shutdown with goroutine tracking. - Enhanced error handling for read and write operations in WebSocket connections. - Created integration tests for shutdown scenarios, including active clients and message handling. - Developed unit tests for error handling, ensuring proper logging and panic recovery. - Introduced WebSocket connection helpers and message utilities in test helpers. - Updated health check tests to use constants for expected responses. - Refactored WebSocket handler tests to improve readability and maintainability.

Pull Request Overview
This PR refactors the server into modular components (hub, client, handlers, config, origin validation, rate limiting, graceful shutdown) and adds extensive cross‑platform build, tooling, and documentation improvements. Key changes focus on security hardening (origin / rate limiting), graceful shutdown, and developer experience (Makefile portability, VSCode tasks, docs).
- Introduces configurable security (origin allow‑list, message size, rate limiting) and graceful shutdown orchestration.
- Splits monolithic server.go into focused files (client, hub, handlers, config, origin, rate_limiter, http server, types) plus added comprehensive test coverage (unit + integration) for lifecycle, errors, and shutdown.
- Adds cross-platform build targets, editor/tooling configs, and detailed documentation (build, cross-platform, graceful shutdown).
