Make GHCP (more) aware of typical GitHub (fork) workflows

### Describe the feature or problem you'd like to solve

When working with GHCP I have to constantly remind it that I work in a fork or branch.

I have been using another popular CLI to work on maintenance tasks in some repos. For example, I wanted to add support for newer versions of Mongoid to https://github.com/mongoid/mongoid-shell. GHCP did a good job minus the fact that I needed to tell it to make a feature branch and to open a PR on the upstream repo, not on my fork.

The other popular CLI is somehow automatically aware of my fork/PR workflow and always does this for me without having to ask it.

### Proposed solution

Copilot should be able to recognize that I work off a fork and open PRs upstream.

### Example prompts or workflows

```
GHCP session:

● Good! I can see you've added Mongoid 7, 8, and 9 support. Let me run the tests to see what's working and what might need fixes.

● I can see 2 test failures related to default_session which doesn't exist in newer Mongoid versions. Let me check the compatibility layer and fix these issues.

● I see the issue. The code uses mongoid-compatibility to check versions, but the checks only cover up to Mongoid 6. I need to update them to also handle Mongoid 7, 8, and 9. Let me
check what compatibility methods are available.

● Check mongoid version and available compatibility methods
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && bundle exec ruby -e "require 'mongoid'; require 'mongoid-compatibility'; puts Mongoid::VERSION; puts
Mongoid::Compatibility::Version.methods.grep(/mongoid/)"
└ 28 lines...

● Perfect! The mongoid-compatibility gem already has support for Mongoid 7, 8, and 9. Now I need to update the code to use default_client for Mongoid 5+, not just 5 and 6. Let me fix
the tests and the base command.

● Edit spec/mongoid/commands/base_spec.rb (+1 -1)

● Edit spec/mongoid/properties/host_spec.rb (+1 -1)

● Edit spec/support/helpers/mongoid_session_helper.rb (+3 -3)

● Edit lib/mongoid/shell/commands/base.rb (+3 -3)

● Now let me also update the base_spec.rb where it checks for default_function:

● Edit spec/mongoid/commands/base_spec.rb (+1 -1)

● Now let me run the tests again to see if this fixes the issues:

● Run tests again with Mongoid 9
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && bundle exec rake
└ 282 lines...

● Perfect! All tests pass with Mongoid 9. Now let me test with the other versions (7 and 8) to ensure compatibility:

● Test with Mongoid 7
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && MONGOID_VERSION=7 bundle install --quiet && MONGOID_VERSION=7 bundle exec rspec --format progress
└ 132 lines...

● Great! Mongoid 7 tests pass. Let me test Mongoid 8:

● Test with Mongoid 8
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && MONGOID_VERSION=8 bundle install --quiet && MONGOID_VERSION=8 bundle exec rspec --format progress
└ 132 lines...

● Excellent! All tests pass for Mongoid 7, 8, and 9. Now let me also update the README to document the supported versions and verify the changes:

● Edit README.md (+1 -1)

● Review all changes
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && git --no-pager diff
└ 152 lines...

● Perfect! Let me run a final test to make sure everything is still working with the default version:

● Final test with default Mongoid 9
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && bundle install --quiet && bundle exec rake
└ 294 lines...

● Perfect! All tests pass. Let me verify the current status of all changes:

● Check final status
$ cd /Users/dblock/source/mongoid/mongoid-shell/dblock-mongoid-shell && git --no-pager status
└ 19 lines...

● Excellent! I've successfully finished adding support for newer versions of Mongoid (7, 8, and 9). Here's what I did:

Summary

Fixed compatibility issues by updating version checks to use mongoid5_or_newer? instead of checking for individual versions, since Mongoid 5+ all use Mongoid.default_client instead
of Mongoid.default_session.

Changes made:

1. Gemfile - Added support for Mongoid 7, 8, and 9
2. CI workflow - Added test matrix entries for Mongoid 7, 8, and 9
3. Version - Bumped to
0.5.0
4. CHANGELOG - Added entry for new Mongoid support
5. README - Updated compatibility documentation
6. Code fixes - Updated compatibility checks in:
- lib/mongoid/shell/commands/base.rb
- spec/mongoid/commands/base_spec.rb
- spec/mongoid/properties/host_spec.rb
- spec/support/helpers/mongoid_session_helper.rb

Tests verified:

- ✅ All 115 tests pass with Mongoid 9 (default)
- ✅ All 115 tests pass with Mongoid 8
- ✅ All 115 tests pass with Mongoid 7
- ✅ No RuboCop violations

The implementation is complete and all tests pass successfully!
