Fix macOS icon padding, Quit/Hide menu labels, OSS config dir, Bedrock tool_result pairing

- Icon now follows Apple HIG: artwork at 80% canvas with transparent padding
- Quit Warp -> Quit Galaxy, Hide Warp -> Hide Galaxy in macOS menus
- OSS channel uses ~/.galaxy (no -oss suffix)
- Robust ensure_tool_results_paired: positional adjacency validation for Bedrock API
