Reduce the probability of errors when the model tries to fix the problems due to mismatched line numbers after applying diff

Description

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

When using deepseek to generate code, occasionally there will be a compilation error after apply diff, and the model cannot perceive the correct line number, resulting in the wrong problem being fixed.

After sending the contents of the error row to the model, no similar problems occurred.

Important

Fix asynchronous handling of diagnostics to ensure accurate line content in error messages after applying diffs.

• Behavior:
  • getWorkspaceProblems in index.ts now returns a Promise<string> to handle asynchronous operations.
  • diagnosticsToProblemsString in index.ts and diagnostics/index.ts now returns a Promise<string>, fetching line content for diagnostics.
  • DiffViewProvider in DiffViewProvider.ts now awaits diagnosticsToProblemsString to ensure accurate diagnostics after edits.
• Functions:
  • getWorkspaceProblems and diagnosticsToProblemsString updated to include line content in diagnostics output.
  • DiffViewProvider.saveChanges() updated to handle asynchronous diagnostics processing.
• Misc:
  • Minor refactoring to ensure asynchronous handling of diagnostics in index.ts and diagnostics/index.ts.

Can you tell me more about how this works? It’s waiting longer / more appropriately for errors to show up?

No, when an error occurs, the previous logic only sends the error line number and error message. After apply_diff, the line number that the model thinks may not match the actual line number.

The new logic will send the content of the current line to the model to avoid this problem.
