fix(translator): normalize tools to Anthropic-native shape for non-Anthropic providers

Browse Source 
Strip `type` field and fold `function.{name,description,parameters}` into
top-level {name, description, input_schema} before forwarding to Claude-format
endpoints. MiniMax (and other Anthropic-compatible providers) reject tools
carrying a `type` field with error code 2013 ("invalid tool type").
