[Backend] Snap Package Manager Implementation

[yashksaini-coder]

Goal

Add full Ubuntu/Snap ecosystem support to TRX.

Description

Implement the PackageManager trait in src/managers/snap.rs using the snap CLI.

Snap-specific considerations:

• Confinement levels: strict, classic, devmode — display this info in the details view
• Channels: Snaps have channels (stable, candidate, beta, edge); expose the tracked channel
• Snap store vs local: Differentiate snaps from the store vs locally installed ones

Required methods:

• search(query) → snap find <query> (parse: Name, Version, Publisher, Notes, Summary columns)
• get_installed() → snap list
• install() → snap install <pkg> (handle --classic flag)
• remove() → snap remove <pkg>
• get_updates() → snap refresh --list
• system_upgrade() → snap refresh

Tech

Rust, Snap CLI

Difficulty

Level 3 – Advanced

@Prateek2007-cmd I don't see your experience with rust.

[yashksaini-coder]

I see javascript, typescript and little bit of C, C is a low level language, but we need people who have work using rust and are familiar with its memory and operations edges, not just writing functions but understand the data flow as well. @Prateek2007-cmd
