Changes

feat: issue #465 add-an-express-error-handler-middleware (agent task liancebot465)

Acceptance Criteria

Add an Express error handler middleware (app.use(errorHandler)) placed after all routes that: (1) In production (NODE_ENV=production), returns generic JSON { error: 'Internal server error' } with status 500, never leaking stack traces or internal details. (2) In development, includes error message and stack for debugging. (3) Logs the full error with structured logging including request path and timestamp. (4) Handles unhandled promise rejections gracefully. Acceptance: no API route can return a raw stack trace in production, all unhandled errors return consistent JSON.

Add centralized error handler middleware with env-aware responses 85a9b1478a

Extracts error handling into dedicated middleware that returns generic
JSON in production (no stack traces), includes debug details in
development, logs structured JSON with path/method/timestamp, and
registers process-level handlers for unhandled rejections and
uncaught exceptions.
