Describe the solution you'd like

Add an Auto Save option for Warp's built-in code editor, similar to what VS Code offers.

Currently, editing files in Warp's native editor requires manual save (CMD+S / CTRL+S) every time. When working alongside Agent Mode or Claude Code, this creates unnecessary friction — you edit a file, switch to the terminal, and realize the file wasn't saved.

Proposed settings (in Settings > Features > Code Editor):

• Off — current behavior, manual save only (default)
• After Delay — auto-save after a configurable delay (e.g. 1000ms)
• On Focus Change — auto-save when switching to another tab, pane, or the terminal
• On Window Change — auto-save when Warp window loses focus

On Focus Change would be the most natural default for a terminal-first workflow, since developers constantly switch between the editor pane and the terminal.

Use case

1. Open a file in Warp's code editor
2. Make a quick edit (rename a variable, fix a typo)
3. Switch to the terminal pane to run a command or continue an agent conversation
4. Expected: file is saved automatically
5. Actual: file remains unsaved (dot indicator on tab), command runs against stale file

This is especially painful when using Agent Mode / CLI coding agents (Claude Code, Codex) that read files from disk — they see the old version unless you remember to CMD+S first.

How important is this feature to you?
