supportsPromptCaching, supportsAdaptiveThinking, supportsThinkingSignature,
and the Claude detection in streamSimpleBedrock/buildAdditionalModelRequestFields
all check model.id for Claude model name patterns. Application inference profile
ARNs are opaque and do not contain the model name, so these checks silently fail.
Fix by also checking model.name (user-controlled via models.json or
registerProvider) as a fallback in all affected functions. Added a shared
isAnthropicClaudeModel helper for the common Claude detection pattern.
Fixes#2925
