Task 40: Support Multiline Paste in codex-rs CLI Input Window

This task is specific to codex-rs.

Acceptance Criteria

• When pasting multiline text into the codex-rs CLI input (REPL), newlines in the pasted text are inserted into the input buffer rather than causing premature command execution.
• The pasted content preserves original end-of-line characters and spacing.
• The user can still press Enter to submit the complete command when desired.
• Behavior for single-line input and manual line breaks remains unchanged.

Implementation

How it was implemented
Provide details on code modules, design decisions, and steps taken.
If this section is left blank or contains only placeholder text, the implementing developer should first populate it with a concise high-level plan before writing code.

How it works
Explain runtime behavior and overall operation.
If this section is left blank or contains only placeholder text, the implementing developer should update it to describe the intended runtime behavior.

Notes

• Investigate enabling bracketed paste support in the line-editing library used (e.g. rustyline, liner).
• Ensure that bracketed paste mode is enabled when initializing the CLI to distinguish between pasted content and typed input.
• Review how other REPLs implement multiline paste handling to inform the design.
