Introduces code.nochebuena.dev/einherjar/httpclient — the outbound HTTP client starter for the Einherjar framework. Absorbs the httpclient package from micro-lib, replacing fmt.Errorf wrapping with core/xerrors and adding generic JSON helpers. Interfaces: - Provider — Do(req *http.Request) (*http.Response, error) Implementation: - New(logger, cfg) Provider — configures net.Dialer + retry + circuit breaker - NewWithDefaults(logger) Provider — convenience constructor with default config - Retry: avast/retry-go; configurable MaxRetries and RetryDelay; retries on network errors and 5xx responses; logs each retry attempt at Warn level - Circuit breaker: sony/gobreaker; opens after CBThreshold consecutive failures within CBTimeout window; returns ErrUnavailable when open - DoJSON[T](ctx, client, req) (*T, error) — executes request, decodes JSON body - DoJSONRequest[Req, Resp](ctx, client, method, rawURL, body) (*Resp, error) — marshals body, builds request, executes, decodes response - MapStatusToError(code, msg) error — maps HTTP status codes to xerrors values Config (EINHERJAR_HTTP_* env vars): Name(http), Timeout(30s), DialTimeout(5s), MaxRetries(3), RetryDelay(1s), CBThreshold(10), CBTimeout(1m) - identifiable.go: package-level Module variable (observability.Identifiable) for version identification — httpclient is a stateless provider; not registered with the launcher
