// CC Sesija A §2.1 Task A4 — shared HTTP helpers for sidecar-proxy commands.

// Extracted from commands/memory.rs at A4 because wiki.rs becomes the second
// consumer (rule of two). Future command modules (onboarding A10+, agent.rs
// where applicable) should also import from here rather than reimplementing.
