fix: installer IDE selection and cancellation handling

- Fix manifest reading to use manifest.yaml instead of manifest.csv
- Show previously configured IDEs as selected by default in UI
- Skip configuration prompts for already configured IDEs during updates
- Properly collect IDE configurations during full reinstall
- Handle installation cancellation without throwing errors
