fix: add _classify_runtime with complete cloud model prefix list (#628 )

`_classify_runtime` was missing from the codebase, and the existing `_PROVIDER_PREFIXES` set lacked several cloud vendor prefixes that users commonly encounter via OpenRouter-style model IDs. Changes: - Add `_CLOUD_MODEL_PREFIXES` frozenset covering all known cloud vendors, including the previously missing: deepseek, cohere, mistral/mistralai, meta-llama, databricks, together, togetherai - Add `_LOCAL_PROVIDER_NAMES` and `_CLOUD_PROVIDER_NAMES` frozensets for provider-name-based classification - Implement `_classify_runtime(model, base_url, provider)` that classifies a runtime as "cloud" or "local" using URL → provider → model-prefix priority - Extend `_PROVIDER_PREFIXES` with the same missing cloud vendors so that `_strip_provider_prefix` also handles cohere:, mistralai:, etc. - Add `TestClassifyRuntime` suite covering all previously-missing prefixes and edge cases Fixes #628 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
