Core Release v1.7.4

feat: added support for Anthropic's fallbacks: "default" preset via the new AnthropicFallbacks wrapper type, preserving it through request round-trips and injecting the server-side-fallback-2026-07-01 beta header for default routing

AnthropicMessageRequest.Fallbacks changed from []AnthropicFallbackEntry to *AnthropicFallbacks. Code constructing this struct directly must wrap entries as &AnthropicFallbacks{Entries: ...}.
feat: added the mid-conversation-tool-changes-2026-07-01 beta header and MidConvToolChanges feature flag for Anthropic and Bedrock Mantle
fix: added Opus 5 support to the Anthropic provider via IsOpus5Plus, inheriting the Opus 4.8 request surface for unsupported sampling params, native effort, fast mode, and mid-conversation system messages
