Pull the private `client`/`postJSON` from `internal/ai` into a standalone `internal/httpclient` package so both the AI providers and the upcoming webhook senders can share the same bounded-reader, timeout-guarded JSON HTTP client without introducing a dependency cycle. Changes: - internal/httpclient: Client struct with PostJSON(ctx, url, headers, payload, out), functional options WithTimeout/WithTransport, a 4 MiB response cap, and a 60s default timeout - internal/ai: three providers (OpenAI, Ollama, Anthropic) now embed an `*httpclient.Client` (field renamed from `client` to `http`); the old `client.go` is deleted - All 11 test packages pass (ai tests are byte-for-byte unaffected) This zero-behaviour refactor unblocks the webhook package distributed in M5, which needs the exact same JSON-post-and-decode helper.
