feat: add snap build target for Linux

[forgou37]

Adds Snap packaging support to the electron-builder Linux configuration.

Changes

• Added snap target (x64 + arm64) to the linux targets in electron-builder.yml
• Added snap: configuration block with:
  • confinement: strict — sandboxed distribution via Snap Store
  • grade: stable
  • Required plugs for screen sharing: x11, wayland, audio-record, audio-playback, camera, network, desktop, opengl, screen-inhibit-control

Usage

pnpm desktop:package:linux
# or specifically:
pnpm build && electron-builder --linux snap

This produces a .snap file in apps/desktop/out/ that can be distributed via the Snap Store or installed locally with snap install --dangerous pairux_*.snap.
