Greptile Summary

This PR fixes drag-and-drop file paths not being pasted correctly into the terminal, specifically for paths that contain spaces (e.g. example image.png). The root cause was that forceBracketedPaste was gated behind hasMultilinePayload, so single-line paths were never wrapped in bracketed paste sequences.

• prompt-injection.ts: The shouldUseBracketedPaste condition is restructured so that forceBracketedPaste: true always enables bracketed paste, regardless of whether the text is single- or multi-line.
• pty-pane.tsx: Drag-and-drop handlers are refactored to use pastePromptInjection with forceBracketedPaste: true, and the path-escaping logic is extracted into a dedicated formatDroppedPaths helper.
• prompt-injection.test.ts: A new test case covers the single-line + forced bracketed paste path.

Confidence Score: 5/5

Safe to merge — the change is narrowly scoped to drag-and-drop path pasting and preserves all existing non-forced bracketed-paste behaviour.

The condition restructuring in buildPromptInjectionPayload is logically equivalent to the old code for every existing call site, and the new single-line forced-paste path is covered by an added test. The trailing space is appended to the already-wrapped payload in the sendInput lambda, so it lands correctly in the terminal after the bracketed-paste end sequence.

No files require special attention.

Important Files Changed

Filename	Overview
src/renderer/lib/pty/prompt-injection.ts	Condition refactored so forceBracketedPaste is independent of hasMultilinePayload; all existing semantics preserved for non-forced paths.
src/renderer/lib/pty/pty-pane.tsx	Drop handler now uses pastePromptInjection with forceBracketedPaste: true; path escaping extracted to formatDroppedPaths; trailing space preserved outside the bracketed-paste sequence.
src/renderer/tests/prompt-injection.test.ts	New test covers single-line content with forceBracketedPaste: true, directly validating the bug fix.
