Chesars 0c27f20692 feat(openai_like): add Responses API support to JSON provider system ...

Add infrastructure for JSON-declared providers to support /v1/responses
via `supported_endpoints` field in providers.json. Simplify Perplexity
responses config from 410 to 40 lines by moving cost dict→float parsing
to generic validators in ResponseAPIUsage and Usage.

- Add `supported_endpoints` field to SimpleProviderConfig (default: [])
- Add `supports_responses_api()` to JSONProviderRegistry
- Create OpenAILikeResponsesConfig base class for responses API
- Add `create_responses_config_class()` with class caching
- ProviderConfigManager: Python classes take priority over JSON fallback
- Fix ResponseAPIUsage.cost field_validator to handle dict cost objects
- Fix Usage.__init__ to handle dict cost from chat completions
- Simplify PerplexityResponsesConfig with get_supported_openai_params guard
- Add 20 unit tests including Python-over-JSON priority test
