Keith Guerin 22cf2a6e91 feat(ui): implement refreshed UX for Composer layout

- Promotes refreshed multi-row status area and footer as the default experience.
- Stabilizes Composer row heights to prevent layout 'jitter' during typing and model turns.
- Unifies active hook status and model loading indicators into a single, stable Row 1.
- Refactors settings to use backward-compatible 'Hide' booleans (ui.hideStatusTips, ui.hideStatusWit).
- Removes vestigial context usage bleed-through logic in minimal mode to align with global UX direction.
- Relocates toast notifications to the top status row for improved visibility.
- Updates all CLI UI snapshots and architectural tests to reflect the stabilized layout.
- Fixes persistent TypeScript compilation errors in tests by refactoring async render helpers (`LoadingIndicator.test.tsx`, `AppHeader.test.tsx`, `ToolMessage.test.tsx`) to avoid direct destructuring of complex inferred return types, ensuring consistent Promise flattening across all CI environments (Node 20/22/24).

Checkpointing

The Gemini CLI includes a Checkpointing feature that automatically saves a snapshot of your project's state before any file modifications are made by AI-powered tools. This lets you safely experiment with and apply code changes, knowing you can instantly revert back to the state before the tool was run.

How it works

When you approve a tool that modifies the file system (like write_file or replace), the CLI automatically creates a "checkpoint." This checkpoint includes:

A Git snapshot: A commit is made in a special, shadow Git repository located in your home directory (~/.gemini/history/<project_hash>). This snapshot captures the complete state of your project files at that moment. It does not interfere with your own project's Git repository.
Conversation history: The entire conversation you've had with the agent up to that point is saved.
The tool call: The specific tool call that was about to be executed is also stored.

If you want to undo the change or simply go back, you can use the /restore command. Restoring a checkpoint will:

Revert all files in your project to the state captured in the snapshot.
Restore the conversation history in the CLI.
Re-propose the original tool call, allowing you to run it again, modify it, or simply ignore it.

All checkpoint data, including the Git snapshot and conversation history, is stored locally on your machine. The Git snapshot is stored in the shadow repository while the conversation history and tool calls are saved in a JSON file in your project's temporary directory, typically located at ~/.gemini/tmp/<project_hash>/checkpoints.

Enabling the feature

The Checkpointing feature is disabled by default. To enable it, you need to edit your settings.json file.

Note: The --checkpointing command-line flag was removed in version 0.11.0. Checkpointing can now only be enabled through the settings.json configuration file.

Add the following key to your settings.json:

{
  "general": {
    "checkpointing": {
      "enabled": true
    }
  }
}

Using the `/restore` command

Once enabled, checkpoints are created automatically. To manage them, you use the /restore command.

List available checkpoints

To see a list of all saved checkpoints for the current project, simply run:

/restore

The CLI will display a list of available checkpoint files. These file names are typically composed of a timestamp, the name of the file being modified, and the name of the tool that was about to be run (e.g., 2025-06-22T10-00-00_000Z-my-file.txt-write_file).

Restore a specific checkpoint

To restore your project to a specific checkpoint, use the checkpoint file from the list:

/restore <checkpoint_file>

For example:

/restore 2025-06-22T10-00-00_000Z-my-file.txt-write_file

After running the command, your files and conversation will be immediately restored to the state they were in when the checkpoint was created, and the original tool prompt will reappear.
