Crate klieo_llm_common 

Provider-agnostic plumbing shared by every klieo-llm-* provider crate.

The Anthropic, OpenAI, Gemini, and Ollama clients all duplicated the same HTTP-client builder and the same reqwest::Error → LlmError mapping. A tuning change had to land in four files; security defaults (TLS redirect policy, connect timeout) could silently drift between providers.

This crate centralises:

• build_http_client + HttpDefaults — single factory with redirects disabled (CWE-200: bearer-token leak via cross-origin redirect).
• map_reqwest — reqwest::Error → LlmError dispatch.
• retry_after_from_headers — RFC 7231 Retry-After parser. Provider crates previously hardcoded retry_after_secs = 1; this lets them honour the upstream’s actual hint.

SSE-event decoding is NOT shared: the frame splitter itself is five lines per crate, and the per-provider event dispatch loop sitting on top is genuinely different (Anthropic typed events, OpenAI choices deltas, Gemini candidates, Ollama JSON-per-line). Sharing the splitter alone would add an abstraction without removing the bulk.
