[Feature] Side-by-Side Package Comparison View

[yashksaini-coder]

Goal

Help users make informed decisions by comparing two packages in a split-screen view.

Description

Allow selecting two packages and pressing a key (e.g., c) to open a comparison view:

┌─ Package A ─────────────┐  ┌─ Package B ─────────────┐
│ Name:    neovim         │  │ Name:    vim             │
│ Version: 0.10.0         │  │ Version: 9.1.0           │
│ Provider: pacman        │  │ Provider: apt            │
│ Description: ...        │  │ Description: ...         │
└─────────────────────────┘  └─────────────────────────┘

Implementation:

1. Add a compare_selection: Option<Package> field to App
2. First c press marks the focused package; second c press opens the comparison view
3. Fetch details for both packages via get_details() and render side-by-side using two Paragraph widgets in a horizontal layout
4. Press Esc to exit the comparison view

Tech

Hi @yashksaini-coder 👋

I'd like to work on this issue under GSSoC'26. I'm familiar with Rust and Ratatui, and I've reviewed the proposed approach. I'll implement:

• Adding compare_selection: Option<Package> to the app state
• Marking a package on first c key press
• Opening a horizontal split comparison view on second c key press
• Rendering package details side-by-side using two Paragraph widgets
• Exit with Esc

Please assign this to me. Thanks!

Hi @Anushreer22
Your implementation plan looks good and matches the requirements of the issue. I've assigned this issue to you. Feel free to open a draft PR early if you'd like feedback during development.

Good luck

Hi! I'd like to work on #78 (CLI Batch / Headless Mode) under GSSoC. The feature seems interesting and I'd love to contribute. Could you please assign it to me? Thank you!
