Phase 6: Migrate MultiSelect and Multiline prompts to huh

Overview

Migrate less common prompt types.

Files

1. internal/prompt/prompt.go:33 - MultiSelect helper
2. internal/prompt/prompt.go:50 - Multiline helper
3. All command files using these helpers

Implementation

// MultiSelect
var selected []string
huh.NewMultiSelect[string]().
    Title("Select labels:").
    Options(
        huh.NewOption("bug", "bug"),
        huh.NewOption("feature", "feature"),
    ).
    Value(&selected).
    Run()

// Multiline (use Text)
var text string
huh.NewText().
    Title("Enter description:").
    Value(&text).
    Lines(5).
    Run()

Success Criteria

• MultiSelect works for label/tag selection
• Multiline text input works with configurable height
• Character limits work if needed
