Fixes #issue where OpenRouter throws a 400 error after 2 tool uses when routing to Anthropic.
Root cause: read_file's nativeArgs was stored as FileEntry[] instead of {files: FileEntry[]} like other tools, causing tool_use.input to be an array instead of an object when added to API conversation history.
Changes:
- Updated NativeToolArgs.read_file to store {files: FileEntry[]} matching API schema
- Updated NativeToolCallParser to wrap files array in object
- Updated ReadFileTool to accept/return object format
- Added debug logging to OpenRouter provider for troubleshooting
All tools now store nativeArgs in their exact API-compatible format, eliminating special-case handling.
