HTTP health check handler with parallel goroutine-per-check execution, 5 s request-derived timeout, and two-level criticality (LevelCritical → 503, LevelDegraded → 200). What's included: - `Checkable` interface (HealthCheck / Name / Priority) and `Level` type with LevelCritical and LevelDegraded constants - `NewHandler(logger, checks...)` returning http.Handler; runs all checks concurrently via buffered channel, returns JSON with per-component status and latency - `ComponentStatus` and `Response` types for the JSON response body Tested-via: todo-api POC integration Reviewed-against: docs/adr/

// Package health provides a stdlib http.Handler for service health checks.
|
|
//
|
|
// Register checkable components and mount the handler at a health endpoint:
|
|
//
|
|
// handler := health.NewHandler(logger, db, cache, queue)
|
|
// r.Get("/health", handler)
|
|
//
|
|
// The handler runs all checks concurrently with a 5-second timeout.
|
|
// It returns HTTP 200 (UP or DEGRADED) or HTTP 503 (DOWN).
