/**
 * HTTP Embedding Client
 *
 * Shared fetch+retry logic for OpenAI-compatible /v1/embeddings endpoints.
 * Imported by both the core embedder (batch) and MCP embedder (query).
 *
 * Network resilience is delegated to `resilientFetch` from
 * `gitnexus-shared` — bounded retries with exponential-backoff jitter,
 * `Retry-After` honored on 429, and an in-process circuit breaker that
 * fails fast on a flapping endpoint. Per-attempt timeout is enforced
 * via `AbortSignal.timeout` on the underlying fetch.
