a90162bafc fix: add _classify_runtime with complete cloud model prefix list (#628)
Some checks failed
Forge CI / smoke-and-build (pull_request) Failing after 36s
`_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
