Module extraction 

EXT-1 — External Extraction Providers.

Implements an ExtractionProvider trait with five concrete backends:

Provider	Transport	Auth
none	—	—
gliner	In-process ONNX	—
openai	HTTPS	Bearer key
openrouter	HTTPS (base_url override)	Bearer key
ollama	HTTP (local)	—
anthropic	HTTPS	x-api-key header

Security contract: api_key fields redact themselves in Debug output and are never serialized (only used at call time via per-request override or server env). They are NOT written to any storage layer.

Provider hierarchy (highest priority wins):

1. Per-request extractor_override in request body
2. Per-namespace default (stored in _dakera_namespace_configs)
3. Server default ([extractor] in config.toml)
4. GLiNER local (if namespace has extract_entities = true)
5. none (default — backward-compatible)
