feature: Add !cmd outputs to model conversation history

Feature: Persist both the LocalShellCall metadata and the FunctionCallOutput from !cmd executions so the model sees each command invocation and its stdout in the conversation history.

Flow: UserShellCommandTask builds a shell ToolCall, lets the runtime run it, then records a LocalShellCall followed by the resulting FunctionCallOutput via Session::record_conversation_items so both items land in the session history.

Abort/Ctrl-C: If the runtime returns "aborted" (the Ctrl-C path) or handle_tool_call errors, we mark the LocalShellCall as Incomplete and emit a FunctionCallOutput with success=false so downstream consumers treat it as a failed or interrupted command.],workdir:/Users/abhishek/code/codex}
