* fix(anthropic): route Claude Opus 4.8 through adaptive thinking Opus 4.8 uses the same adaptive thinking contract as 4.6/4.7 (thinking.type=adaptive plus output_config.effort), but _is_adaptive_thinking_model only recognized 4.6/4.7 by name and otherwise leaned on the supports_adaptive_thinking cost-map flag. The Bedrock, Vertex, and Azure 4.8 entries don't carry that flag, so a bedrock/us.anthropic.claude-opus-4-8 request fell back to the legacy thinking.type=enabled shape and Bedrock rejected it with "thinking.type.enabled is not supported for this model". Add _is_claude_4_8_model and wire it in next to the existing 4.6/4.7 matchers in the adaptive-thinking detection, the effort=max gate, and the supported-params check, so every provider path treats 4.8 as adaptive regardless of whether its cost-map entry advertises the flag. * refactor(anthropic): drive Opus 4.8 adaptive thinking from the cost map Replace the _is_claude_4_8_model name matcher with cost-map data. Add supports_adaptive_thinking to every Opus 4.8 provider variant (Bedrock regional/global, Vertex, Azure) in both the root and bundled cost maps, and move the prefix-resolving capability lookup (_supports_model_capability) down to AnthropicModelInfo so _is_adaptive_thinking_model reads the flag through the bedrock/invoke/, bedrock/, and vertex_ai/ prefixes. The 4.6/4.7 name checks stay as a fallback since their provider entries don't carry the flag yet. A pure data fix is not enough on its own: _supports_factory doesn't strip the us.anthropic./invoke/ prefixes, so bedrock/invoke/us.anthropic.claude-opus-4-8 would still miss the flag without the resolver change. Add a cost-map guardrail test asserting every claude-opus-4-8 variant carries the flag, so a future variant added without it fails CI instead of silently sending the legacy thinking.type=enabled shape that the provider rejects.

[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
