Phase 3: Migrate Input and Password prompts to huh

Overview

Migrate text input and password prompts.

Files to Migrate

1. internal/commands/auth/login/login.go:272 - Input: Hostname
2. internal/commands/auth/login/login.go:278 - Input: API Host
3. internal/commands/auth/login/login.go:345 - Input: Hostname
4. internal/commands/auth/login/login.go:529 - Password: Token (with validation)

Implementation

// Input
huh.NewInput().
    Title("GitLab hostname:").
    Value(&hostname).
    Placeholder("gitlab.com").
    Run()

// Password with validation
huh.NewInput().
    Title("Paste your authentication token:").
    Value(&token).
    EchoMode(huh.EchoModePassword).
    Validate(func(s string) error {
        if s == "" { return fmt.Errorf("required") }
        return nil
    }).
    Run()

Success Criteria

• Text inputs work with defaults/placeholders
• Password masking works
• Required validation works
