- Makefile: -include .env (soft) so fresh clone doesn't hard-fail
- main.go: replace log.Fatalf-in-goroutine with error channel; startup
failures now reach main goroutine so defer pool.Close() always runs
- main.go: context.WithTimeout(30s) on database.Connect to fail fast
instead of hanging indefinitely on unreachable Postgres
- router.go: store pool on Echo context via middleware so future story
handlers can retrieve it with c.Get("pool")
- config.go: require DATABASE_URL explicitly (log.Fatal if missing)
instead of falling back to hardcoded credentials
- HelloWorld.test.ts: URL-aware fetch stub + afterEach restoreAllMocks;
add flushPromises test verifying backend status renders
