[Feature Request] Add “Paste w/o executing newlines” (treat \n as text)

What feature would you like to see?

Background

When pasting multiline text (e.g., code snippets, prompt templates, or structured parameters) into input fields, editors, or terminals, the current behavior often interprets newline characters as execute/send triggers, or splits the content into multiple commands. This leads to accidental runs, broken formatting, or premature submissions.

What I want

Introduce an alternative paste mode where newlines are treated strictly as text. Optionally, add a mode to escape newlines (replace them with literal \n).

Use cases

Pasting a multiline prompt into a chat input without auto-sending.

Pasting multiline commands into a REPL/terminal, but reviewing them before executing.

Pasting structured text (e.g., JSON, regex, scripts) with embedded newlines that should remain intact or be escaped.

Expected behavior

Provide configurable paste modes (via shortcut, context menu, or settings):

A. Single-line paste: Replace \r?\n with a space.

B. Escaped paste: Replace real newlines with literal \\n (optionally escape \t as \\t).

C. No-exec paste: Preserve newlines exactly but guarantee that no auto-send/a
