Add Arch Linux installation instructions

[Antony-hash512]

Added installation instructions for Arch Linux.

Summary

Added the necessary pacman command to install required build dependencies for Arch Linux users. This helps to avoid linker errors (specifically missing libxdo / xdotool required for global shortcuts) when building the Tauri frontend on Arch-based distributions.

Changes

• Updated docs/install/linux.md to include Arch Linux dependencies (base-devel, webkit2gtk-4.1, libayatana-appindicator, librsvg, openssl, xdotool).
• Added the --needed flag to the pacman command to prevent reinstalling already up-to-date packages.

Type

• 🐛 Bug fix
• ✨ New feature
• ♻️ Refactor
• 📝 Documentation
• 🧪 Tests
• 🔧 CI / Build
• 🚀 Release prep (RC or final)

Testing

• Verified the build process locally on Arch Linux.
• Confirmed that installing these packages successfully resolves the rust-lld: error: unable to find library -lxdo error during bun run desktop-prod.

Checklist

• I've tested this locally
• I've updated relevant documentation (if applicable)
• No local machine paths, logs, or personal env details in this PR
• Version files are in sync (if version bump): pyproject.toml, package.json, tauri.conf.json, Cargo.toml
• If this PR changes runtime behavior, the regression fixture at tests/fixtures/omnivoice_data/ still loads green on the smoke-matrix CI job (macOS + Windows + Linux)
• If this is part of a release, I've read the "Release cadence" section below and confirmed this PR targets the right RC

Summary by CodeRabbit

• Documentation
  • Updated Linux installation prerequisites to add Arch Linux-specific instructions for installing GTK and WebKit runtime dependencies required by the desktop shell. This clarifies required packages and installation steps for Arch users, aligning Arch guidance with existing Debian/Ubuntu and Fedora notes to reduce setup friction and improve installation success on Arch systems.

Greptile Summary

This PR adds Arch Linux package installation instructions to the Linux prerequisites section of docs/install/linux.md. The packages listed correctly resolve the rust-lld: error: unable to find library -lxdo linker error reported by Arch users building the Tauri frontend.

• Added sudo pacman -S --needed base-devel webkit2gtk-4.1 libayatana-appindicator librsvg openssl xdotool under a new # Arch comment inside the existing GTK/WebKit deps code block.
• Package mapping is accurate: base-devel → build-essential, webkit2gtk-4.1 → libwebkit2gtk-4.1-dev, xdotool (which bundles libxdo.so on Arch) → libxdo-dev, and the remaining three packages mirror their Debian/Fedora counterparts correctly.
• The --needed flag is placed in the conventional position (after -S, before package names), consistent with standard Arch Linux documentation style.

Confidence Score: 5/5

Documentation-only change; no runtime behaviour is affected and the package list is accurate.

The diff is three lines of Markdown inside a fenced code block. The Arch package names correctly map to every dependency listed for Debian/Ubuntu. On Arch, xdotool ships libxdo.so in the same package (unlike Debian's split libxdo-dev), so the mapping resolves the reported linker error. No code, configuration, or runtime behaviour is touched.

No files require special attention.

Important Files Changed

Thanks @Antony-hash512 — this is a clean fix that fills a real gap (the install doc already listed Arch in the intro but had no pacman command). The package set maps 1:1 to the existing Debian/Fedora instructions, and xdotool is exactly what resolves the -lxdo linker error for global shortcuts. Merging. 🙏
