feat: OpenAI, Anthropic, and native-Ollama providers + media pipeline
Phase 3:
- provider/openai: Chat Completions for OpenAI + compat endpoints (SSE
streaming with by-index tool-call assembly, response_format json_schema,
legacy max_tokens option, reasoning_effort)
- provider/anthropic: Messages API (tool_use/tool_result, GA structured
output via output_config.format, full SSE event parser, 529 transient)
- provider/ollama: one native /api/chat client behind the ollama,
ollama-cloud, and foreman built-ins (presets; NDJSON streaming tolerant
of foreman's buffered single-object responses; object tool arguments;
format-schema structured output; think mapping)
- media/: capability normalization (sniff, downscale, transcode, byte
ladder, ErrUnsupported), wired into the chain executor per target with
penalty-free advance past incapable elements
- registry: real provider + scheme wiring, WithHTTPClient option, required
env-foreman TLS chat round-trip test
- ADR-0009 multimodal strategy, ADR-0010 tools/structured mapping; README
matrix + CLAUDE.md synced
