Summary by cubic

Cmd+Shift+Enter now accepts all pending diffs in the visible file, not just the first block. Other files with diffs stay open so you can accept them next.

• Bug Fixes
  • Processes one file at a time via processSingleFileDiff; selects the visible/first pending file from VerticalDiffManager.getAllFilesWithDiffs().
  • Keeps remaining diffs visible by setting continue.diffVisible based on leftover handlers; only refocuses input when none remain.
  • Invokes cancelApply only on reject while preserving edit outcome tracking and auto-format detection.

@uinstinct I think since you can only see one diff at a time it should only accept the current diff

P2: The global document change listener is always disposed in clearForfileUri even when other file diffs remain, so multi-file diff tracking stops for remaining files. The listener should only be disabled when no diffs remain.
