Codex tools on the Responses to Chat bridge

Codex CLI sends its tools inside an additional_tools input item instead of top-level tools. The Responses API to Chat Completions bridge dropped that item, so bridged models such as Bedrock Converse never saw a tool and Codex could not run shell commands

• additional_tools input items are now hoisted into tools for every bridged provider, and Bedrock Mantle reuses the same helper
• custom tools nested inside a namespace, such as Codex's exec shell tool, now convert to chat tools
• The model's call comes back to Codex as a custom_tool_call, the same way for streaming and non-streaming responses
• Guardrail edits after a custom tool's grammar block land on the tool instead of being applied twice

See the Codex CLI setup guide

What's Changed

• Hoist Codex additional_tools input items into the chat bridge tools - PR #40989, backported in PR #45212
