Summary

Adds a ProviderType.OPENROUTER branch to ProviderRegistry._create_provider_llm() so that create_llm("openrouter") returns a configured ChatOpenAI instance instead of raising ValueError: Unsupported provider type: openrouter
Fixes agents actor run openrouter/<model> failures caused by SimpleLLMAgent._resolve_llm() calling create_llm() rather than create_ai_provider()
Adds comprehensive BDD scenarios covering the new branch: basic client construction, header sanitization, create_llm() delegation, organization headers, default model fallback, empty headers, extra kwargs forwarding, and empty API key validation

Motivation

create_ai_provider("openrouter") correctly instantiated OpenRouterChatProvider, but create_llm("openrouter") — used by SimpleLLMAgent in the reactive stream router — fell through the provider dispatch chain to raise ValueError(f"Unsupported provider type: {provider_type}"). All seven other providers (OpenAI, Anthropic, Google/Gemini, Azure, Groq, Together, Cohere) had branches; OpenRouter was the only one missing.

Approach

src/cleveragents/providers/registry.py: Added OPENROUTER branch in _create_provider_llm():

Creates ChatOpenAI with openai_api_base="https://openrouter.ai/api/v1" and openai_api_key from settings
Handles optional default_headers kwarg — sanitizes mapping to dict[str, str] via inline comprehension (avoids ruff import-order violation from importing OpenRouterChatProvider._sanitize_headers)
New (review fix M1): Reads openrouter_organization from settings and injects HTTP-Referer and X-Title headers, matching OpenRouterChatProvider.__init__() behavior
New (review fix m1): Explicit ValueError guard when openrouter_api_key is empty/missing, consistent with OpenRouterChatProvider
Follows the existing single-import-per-branch pattern used by all other providers

features/provider_registry_coverage.feature: Nine @unit @providers @registry scenarios (expanded from three):

_create_provider_llm builds OpenRouter client with ChatOpenAI — verifies model, openai_api_base, and openai_api_key (M2 fix)
_create_provider_llm builds OpenRouter client with sanitized default headers — verifies numeric keys/values are coerced to strings, original integer key 123 is absent (m7 fix), and openai_api_key is passed (m8 fix)
create_llm succeeds for OpenRouter and delegates to _create_provider_llm — verifies the dispatch chain
_create_provider_llm adds organization headers for OpenRouter — verifies HTTP-Referer and X-Title are injected from openrouter_organization setting (M1 fix)
_create_provider_llm uses default model for OpenRouter when model_id is None — verifies fallback anthropic/claude-sonnet-4-20250514 (m2 fix)
_create_provider_llm treats empty default_headers as None for OpenRouter — verifies default_headers={} results in no default_headers key passed to ChatOpenAI (m4 fix)
_create_provider_llm forwards extra kwargs to ChatOpenAI for OpenRouter — verifies temperature=0.7 is forwarded via kwargs (m5 fix)
_create_provider_llm raises error when OpenRouter API key is empty — verifies explicit ValueError with OPENROUTER_API_KEY mention (m1 + m6 fix)

features/steps/provider_registry_steps.py: Added step definitions for new scenarios (no-model call, empty headers, temperature kwarg, negative header assertion, no-default-headers assertion, numeric value comparison in stubbed argument check).

CHANGELOG.md: Entry added to ### Fixed section.

## Summary - Adds a `ProviderType.OPENROUTER` branch to `ProviderRegistry._create_provider_llm()` so that `create_llm("openrouter")` returns a configured `ChatOpenAI` instance instead of raising `ValueError: Unsupported provider type: openrouter` - Fixes `agents actor run openrouter/<model>` failures caused by `SimpleLLMAgent._resolve_llm()` calling `create_llm()` rather than `create_ai_provider()` - Adds comprehensive BDD scenarios covering the new branch: basic client construction, header sanitization, `create_llm()` delegation, organization headers, default model fallback, empty headers, extra kwargs forwarding, and empty API key validation ## Motivation `create_ai_provider("openrouter")` correctly instantiated `OpenRouterChatProvider`, but `create_llm("openrouter")` — used by `SimpleLLMAgent` in the reactive stream router — fell through the provider dispatch chain to `raise ValueError(f"Unsupported provider type: {provider_type}")`.

This PR adds comprehensive support for OpenRouter in ProviderRegistry._create_provider_llm(), including: API key validation, header sanitization, organization header injection, default model fallback, and forwarding extra kwargs. Comprehensive BDD scenarios and step definitions cover all new behavior, and the CHANGELOG has been updated accordingly. All Quality Gates pass and CI is green. No blocking issues were found.

Suggestions: consider refactoring header sanitization and organization header logic into a shared helper for consistency across providers, and verify import paths for ChatOpenAI match other provider branches for uniformity.
