Interactive Mode

## How It Works

The interactive picker displays all branches in a smart order:

1. **Recent branches first** - Branches you've visited recently appear at the top (up to 20)
2. **Remaining branches alphabetically** - All other branches are sorted alphabetically
3. **Current branch marked** - Your current branch is marked with `(current)`

<Note>
  The picker remembers your branch history using state stored in `.git/git-switch.json`.
</Note>

## Navigation

The fuzzy picker is powered by `dialoguer` and supports:

<Steps>
  <Step title="Type to filter">
    Start typing any part of the branch name to filter the list in real-time
  </Step>
  
  <Step title="Navigate with arrows">
    Use `↑` and `↓` arrow keys to move through filtered results
  </Step>
  
  <Step title="Select with Enter">
    Press `Enter` to switch to the selected branch
  </Step>
  
  <Step title="Cancel with Ctrl+C">
    Press `Ctrl+C` or `Esc` to exit without switching
  </Step>
</Steps>

## Real-World Example

```bash
$ gitsw
? Select branch
> main (current)
  feature-auth
  feature-api
  develop
  bugfix/user-login
  hotfix/security-patch

$ gitsw
? Select branch api
> feature-api

## Implementation Details

From `src/prompt.rs:22-74`, the interactive picker:

```rust
pub fn select_branch() -> Result<String> {
    let repo = GitRepo::open()?;
    let state = StateManager::load(repo.git_dir())?;
    let all_branches = repo.list_branches()?;

    // Get recent branches from state
    let recent = state.recent_branches(20);
    
    // Sort branches: recent first, then alphabetically
    let mut branches: Vec<String> = Vec::new();
    
    // Add recent branches first (that still exist)
    for name in &recent_names {
        if all_branches.contains(&name.to_string()) {
            branches.push(name.to_string());
        }
    }
    
    let selection = FuzzySelect::with_theme(&ColorfulTheme::default())
        .with_prompt("Select branch")
        .items(&display_branches)
        .default(0)
        .max_length(15)
        .interact()?;
}

# These will still use interactive mode if no branch is specified
gitsw -p    # Pick branch interactively, then pull
gitsw -c    # Cannot be used in interactive mode (requires branch name)
