Summary by cubic

Automatically accepts agent edit tool diffs when the auto-accept setting is enabled, skipping confirmation for Edit Existing File, Single Find & Replace, and Multi Edit calls. Addresses Linear CON-3918 to reduce friction in agent-led edits.

• New Features
  • Checks ui.autoAcceptEditToolDiffs during tool call handling.
  • Auto-approves EditExistingFile, SingleFindAndReplace, and MultiEdit when enabled.

@uinstinct I agree YOLO mode should be expanded to include policies. With this implementation the policy behavior would conflict with the tool policy in the settings page. I think we could do this approach but only if we also show UI (maybe a tooltip/icon) to indicate that the tool policy is forced to automatic by the auto accept edits setting (and show it as automatic and disabled in the policies)
