✨ Diagnostic Manager

Bắt đầu bằng cách xác định các component Issue Navigator và Line Annotations của editor, sau đó lần theo cách chúng hiện đang nhận dữ liệu chẩn đoán. Xác định DiagnosticManager và DiagnosticIssue dựa trên các yêu cầu, nhóm các cập nhật theo file và các thay đổi có thể quan sát được; công việc được xem là hoàn tất khi cả hai component đều có thể sử dụng manager làm nguồn chẩn đoán dùng chung.

Description

Introduce a DiagnosticManager responsible for managing and publishing diagnostics (e.g., build errors, linter warnings, language server issues) grouped by file. This manager will serve as the single source of truth for diagnostics across the editor, and its contents will drive visual components such as the Issue Navigator and Line Annotations.

Requirements

• Create a DiagnosticManager class conforming to ObservableObject
• Store diagnostics as a flat list or grouped by file:

  @Published var issues: [DiagnosticIssue]
  

• Define a DiagnosticIssue model:

  struct DiagnosticIssue: Identifiable, Hashable {
      let id: UUID = UUID()
      let file: URL
      let line: Int
      let column: Int?
      let message: String
      let severity: Severity
      let source: String?
      let fixItSuggestion: String?
  
      enum Severity {
          case error, warning, info, live
      }
  }
  

• Add convenience accessors:

  var issuesByFile: [URL: [DiagnosticIssue]]
  func issues(for file: URL) -> [DiagnosticIssue]
  

• Add a way to update issues by file, e.g.:

  func setIssues(_ issues: [DiagnosticIssue], for file: URL)
  func clearIssues(for file: URL)
  

Additional Context

This manager will be used by multiple parts of the app, including the Issue Navigator and Line Annotations. It should be reactive and efficient, allowing UI components to automatically update when diagnostics change.

Future extensions may include filtering, debouncing updates, or supporting different diagnostics sources (build system, LSP, etc.).
