Raise default dial timeout 500ms -> 2s

// DefaultDialTimeout is the per-host TCP connect timeout. Short by default
// so failover paths skip dead nodes quickly; override via
// ENTIRE_CONNECT_TIMEOUT_SECONDS on slow links where the dial trips before
// the node can answer.
const DefaultDialTimeout = 500 * time.Millisecond
// so failover paths skip dead nodes quickly, but long enough to absorb a
// slow initial connect (cold DNS, TLS-fronting LB, distant region) that a
// tighter budget would trip; override via ENTIRE_CONNECT_TIMEOUT_SECONDS on
// slow links where even this trips before the node can answer.
const DefaultDialTimeout = 2 * time.Second

// DialTimeout returns the configured dial timeout, honoring
// ENTIRE_CONNECT_TIMEOUT_SECONDS. Invalid values fall back to
