fix(buckets|scoop-install): Handle cases when Git is unavailable

[z-Fng]

Motivation and Context

Fix two issues that occur when Git is not installed:

1. new_issue_msg crashes when trying to invoke Git commands, leading to confusing error messages and incorrect issue links.
   e.g. [Bug] difficulty downloading 7zip #6588
   [Bug] Cannot install 7zip and git #4735
   [Bug] Scoop fails to install 7zip with error 1601 - Windows 2025 Server #6562

• After:

2. Scoop update triggers a 'git required' error even when users are trying to install git itself.

• Before:
• After:

Changes:

• lib/buckets.ps1: Check Test-GitAvailable before invoking Git in new_issue_msg.
• libexec/scoop-install.ps1: Skip Scoop update when Git is not available.

Checklist:

• I have read the Contributing Guide.
• I have ensured that I am targeting the develop branch.
• I have updated the documentation accordingly.
• I have updated the tests accordingly.
• I have added an entry in the CHANGELOG.

Walkthrough

These changes add handling for scenarios where Git is unavailable. A Test-GitAvailable check is introduced to prevent Git operations when Git is not installed or inaccessible. Updates span the changelog, bucket handling logic, and Scoop installation workflow.

Changes

Cohort / File(s)	Summary
Documentation CHANGELOG.md	Added changelog entry documenting the new Git availability handling feature under the Unreleased section.
Git Availability Checks lib/buckets.ps1, libexec/scoop-install.ps1	Added Test-GitAvailable conditions to prevent Git operations when Git is unavailable. In buckets.ps1, remote URL extraction is skipped if Git is absent. In scoop-install.ps1, the outdated Scoop warning triggers when Git is not available instead of proceeding to update.

Poem

🐰 When Git plays hide-and-seek,
Our buckets don't weep,
We check, we prevent, we're quite slick,
No crashes, no tricks—
Just graceful handling, chic! 🌟

The "scoop install git" command works just fine. Because the main bucket is already included with scoop as a normal non-git folder, which in return contains the manifest to install git. Once the main bucket is updated after fit is installed, the main bucket also gets converted to git.

I'm not saying that is necessarily the best solution. I would prefer it if git (and 7zip) was always installed and the main bucket was synced with git in the first place.

But it's not broken by default when scoop is installed.

If your git it broken, better to reinstall scoop.

This proposed solution is pure AI slop which does nothing.

The only change I'd advocate for is for either git (and 7zip) to be installed by default, or git (and 7zip) to be installed automatically once a command requiring git is run, rather than throwing an error and having to install it manually.

I think you missed the point of what I'm actually fixing here, and it's very rude of you to call this 'AI slop' before you've even figured out what problem I'm solving.

Scoop supports using external Git and 7zip installations. The assumption that 'git (and 7zip) was always installed by scoop' simply doesn't hold true for all users. Real-world scenarios are more complex than that—some errors even occur during installation, and the issue I'm addressing causes the error messages to be confusing. Reinstalling might clear the state, but it doesn't fix the logic gap that causes this confusing error in the first place.

My apologies, I completely misunderstood what you were trying to achieve, and for my tone.

I thought that you were actually trying to remediate the fact that git is not installed by default and that coderabbit make a fix which didn't actually do that.

Actually you were just making some edge case error messages more user friendly.

Which is a noble goal, but why not be more ambitious to actually provide a remediation for the elephant in the room that scoop doesn't install git automatically when needed?

Just seems like extra work for the user, and doesn't seem that hard to implement.

maybe something like this?

update the Test-GitAvailable in lib/core.ps1:

function Test-GitAvailable {
    # Check if git is available
    if ([Boolean](Get-HelperPath -Helper Git)) {
        return $true
    }

    # Git not found - attempt auto-install
    warn "Git is required but not installed. Installing git..."
    & "$PSScriptRoot\..\libexec\scoop-install.ps1" 'git'

    # Check again after install
    if ([Boolean](Get-HelperPath -Helper Git)) {
        success "Git installed successfully"
        return $true
    }

    # Install failed
    return $false
}

bin/scoop.ps1 lines 23 & 34 replace:

Test-GitAvailable

with

([Boolean](Get-HelperPath -Helper Git))
