feat: add Arch/Manjaro Linux support to setup.sh

[DashratRajpurohit]

Fixes #1381

Description

This PR adds a detection and package installation branch for Arch-based Linux distributions (e.g., Arch Linux, Manjaro, Mabox Linux, EndeavourOS) in scripts/setup.sh.

Changes Included:

• Added detection branch for Arch/Manjaro systems (/etc/arch-release, /etc/manjaro-release, or pacman command).
• Added system dependency package installation via pacman:
  • webkit2gtk-4.1 (Tauri WebView engine)
  • base-devel (Development build tools)
  • curl, wget, file, openssl, librsvg
  • xdotool (Provides libxdo headers/libs)
  • libayatana-appindicator (System indicator support)
  • nodejs & npm (In Arch Linux, npm is packaged separately from nodejs)
  • rustup & pyenv

Verification:

• Verified script syntax using bash -n scripts/setup.sh.
• Verified local environment initialization on Arch-based Mabox Linux.

Summary by CodeRabbit

• New Features
  • Added setup support for Arch Linux and Manjaro systems.
  • The setup process now detects Arch-based Linux distributions and installs required application, build/graphics libraries, Node.js/npm, Rust, and Python tooling using the appropriate package managers.
• Bug Fixes
  • Improved error messaging when the Linux distribution is unsupported, including an updated list of supported platforms.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Walkthrough

The setup flow now recognizes Arch-based distributions, including Manjaro, and installs their required system packages with pacman before reaching the unsupported-platform fallback.

Changes

Arch-based setup support

Layer / File(s)	Summary
Arch detection and setup routing scripts/setup.js	Adds Arch and Manjaro release-file checks and updates unsupported Linux and operating-system messages to list Arch-based systems.
Arch dependency installation scripts/setup.sh	Adds a pacman branch that installs WebKit, build, networking, X11, appindicator, SVG, Node.js, and npm packages.

Poem

I’m a small rabbit hopping through Arch,
Packages bloom beneath the moonlit march.
WebKit and Node join the parade,
While Manjaro’s setup gets neatly made.
Hop, hop—no unsupported trail today!

recognize Arch-based distributions consistently with the Arch branch in
setup.sh, ensuring the supported setup command can reach it. In the pacman
dependency list, remove rustup and pyenv while leaving their initialization to
the existing later bootstrap logic; if Arch support is not intended, remove the
entire Arch branch instead.

Avoid partial upgrades on Arch Linux.

Using pacman -Sy without -u refreshes the package database and installs new packages against it, which can cause partial upgrades. Partial upgrades are explicitly unsupported on Arch Linux and can lead to a broken system (e.g., shared library incompatibilities).

Consider using pacman -Syu to upgrade the system alongside the installation, or simply pacman -S to install using the existing synced databases. Using pacman -Syu is the safest approach for ensuring compatibility.
