A new user's computer had no Git, so Lite could not work there. Git and the GitHub CLI are the last things a fresh macOS, Windows, or Linux computer lacks after #287.

Git (agents run it on nearly every task; GitHub clones and worktrees need it)

• Installing any harness first installs Git when it is missing, through each system's own installer, which asks for administrator approval in its own window:
  • macOS: xcode-select --install (Apple's Command Line Tools), then Lite waits up to an hour for xcode-select -p to succeed.
  • Windows: winget install Git.Git. refresh_user_path now reads the Machine PATH as well, so Lite finds the new git without restarting.
  • Linux: pkexec with apt-get, dnf, zypper, or pacman, whichever exists.
• Git is best-effort for a harness install: if Git fails, the agent still installs, while Cancel stops both. This replaces the Kimi-only Git for Windows step from Install every harness on a brand-new computer (0.0.94) #287.

GitHub CLI

• "Sign in with GitHub CLI" stopped with "Could not find gh in your PATH". It now calls prepare_github first, which installs Git and then unpacks GitHub's release build of gh (latest tag from the releases API, archive for this OS and architecture) into ~/.local/bin, with no administrator needed. A toast with Cancel appears if setup takes more than half a second.

Shared installer

• The spawn, stderr capture, and cancel logic moves out of install_agent into run_installer, and the PowerShell/sh wrapper with the curl→wget fallback into installer_shell, so Git, gh, and harness installs share one cancellable path.

Validation (macOS)

• The exact gh command, run with an empty HOME and PATH=/usr/bin:/bin, installs gh version 2.103.3.
• The exact Command Line Tools wait loop and Linux package-manager loop, run against fake xcode-select, dnf, and no-manager PATHs, behave as intended.
• cargo clippy, cargo fmt --check, cargo test, bun run check, and bun test pass.
• The Windows and Linux branches are compiled by CI and not yet run on a real machine.

🌟 Summary

Lite now prepares Git before installing an agent and sets up the GitHub CLI before GitHub sign-in, supporting computers where those tools are missing.

📊 Key Changes

• Added Git setup for macOS via Apple Command Line Tools, Windows via winget, and Linux via pkexec with supported package managers; Git setup is best-effort for agent installs.
• Added prepare_github, which checks for GitHub CLI and, if missing, downloads the latest release for the current OS and architecture into ~/.local/bin.
• Moved installer execution, error capture, and cancellation into shared helpers, and serialized installer and GitHub setup runs.
• Updated Windows PATH refresh to include the Machine PATH and filtered empty PATH entries so they cannot supply a CLI.

🎯 Purpose & Impact

• A missing Git or GitHub CLI can now be handled as part of agent installation or GitHub sign-in; GitHub setup shows a cancellable loading toast if it takes more than 500 ms.

Reviewed Git and GitHub CLI installation, cancellation, and PATH handling. The Windows PATH refresh can introduce a current-directory executable lookup when the User PATH is empty; otherwise, no concrete issue found.

💬 Posted 1 inline comment

• 💡 MEDIUM src-tauri/src/lib.rs:3509 If the Windows User PATH is empty or unset, this concatenation starts with ;. user_path() later splits that PATH, and resolve_executable() checks each entry in order; the empty entry resolves against Lite’s current directory, so a git.exe or provider executable there can run ahead of the Machine PATH entry. Build the refreshed PATH from nonempty values and filter empty components before caching it.

Fixed in 63a8c77: user_path() now drops empty entries, so neither a leading ; nor a ;; inside a PATH can resolve against the current folder.

🎉 Huge thanks to @glenn-jocher for the merged PR!

This brings Git and GitHub CLI setup together with agent installation and GitHub sign-in, helping Lite handle computers where those tools are missing.
