Task: E2E test - Full workflow (open epic → expand → click task → view/sync progress)

Description

Create an end-to-end test that validates the complete user workflow from opening the extension, browsing epics, viewing task details, updating status, and syncing with GitHub. This test ensures all components work together seamlessly in a real-world scenario.

Acceptance Criteria

• Test opens VSCode with extension activated
• Test expands Epic tree view
• Test clicks on task to open details
• Test views task in progress panel
• Test updates task status via command
• Test syncs task to GitHub
• Test verifies GitHub issue created/updated
• Test validates UI updates after sync
• All workflow steps complete successfully

Technical Details

• Create test file: test/e2e/fullWorkflow.test.ts
• Test workflow steps:
  1. Activate extension in test VSCode instance
  2. Verify tree view registered and visible
  3. Expand epic node in tree view
  4. Verify task nodes displayed
  5. Click task node to open file/panel
  6. Verify progress panel opens with task details
  7. Execute status update command (open → in_progress)
  8. Verify frontmatter updated in file
  9. Verify tree view icon updated
  10. Execute GitHub sync command
  11. Verify GitHub API called with correct data
  12. Verify GitHub issue link added to frontmatter
  13. Verify success notification shown
  14. Execute sync again (update existing issue)
  15. Verify GitHub issue updated
• Use @vscode/test-electron for full extension testing
• Create complete test workspace with epic/task files
• Mock GitHub API for predictable responses
• Capture screenshots at each step for debugging
• Use retry logic for timing-sensitive operations
• Files affected: test/e2e/*.test.ts (new)
