Changelog v2.4.0 - Automated Testing Infrastructure

Release Date: 2026-04-10 Summary: Milestone update establishing a professional testing workflow for pre-deployment validation.

🛡️ Testing & Validation

• Pre-Flight Suite: Introduced tests/api_check.js, an automated integration script that verifies all core API endpoints, authentication layers, and message dispatching.
• Color-Coded Reports: Provides immediate visual feedback in the terminal for system health.

🧹 Security & Housekeeping

• Developer Exclusions: Updated .gitignore to prevent development-only tools like tests/ and scripts/ from being pushed to public or production environments.
• Auth Integrity: The test suite validates the x-api-key header implementation across all sensitive routes.

🏗️ Architecture

• Version Bump: Increment to v2.4.0, providing the "Pre-Flight" safety net required for the upcoming Dashboard Phase.
