Now I have enough context to generate the documentation update summary:

## Documentation Update Summary

### Changes Made
| File | Change | Related Code |
| --- | --- | --- |
| `docs/src/ai/edit-prediction.md` | Updated GitHub Copilot sign-in instructions to describe the new popup window flow with device code display, copy button, and "Connect to GitHub" button | PR #30239 (`e9a756b5fc`) |
| `docs/src/ai/edit-prediction.md` | Updated Codestral setup instructions to direct users to Settings Editor → Edit Predictions instead of Agent Panel | PR #44505 (`0283bfb049`) |

### Rationale
These documentation updates reflect two UI changes in Zed:

1. **Copilot Sign-in Flow**: The sign-in process was redesigned from a simple status bar prompt to a dedicated popup window (`CopilotCodeVerification`) that displays the device code with copy functionality and a "Connect to GitHub" button. The window auto-closes on successful authorization. The previous documentation was too vague ("follow the setup instructions").

2. **Codestral Configuration**: Edit prediction providers can now be configured through the graphical Settings Editor rather than requiring users to navigate to the Agent Panel settings view. This provides a more discoverable and consistent configuration experience.

### Review Notes
- **Keyboard shortcuts**: The Codestral section now includes platform-specific shortcuts (`Cmd+,` / `Ctrl+,`). Reviewers should verify these match the current keybindings.
- **Consistency**: Both changes improve documentation specificity by describing exact UI elements rather than generic "follow instructions" language.
- **No skipped changes**: All planned updates from Phase 4 were successfully applied.
- **Formatting verified**: File passes Prettier 80-character line width check.
