Add color-eyre to workspace

The test_error_backwards_compatability is failing for cargo test --all --no-default-features.

The test is very complex and has failed in the past when rust std added another function in the backtrace due to some internal change.

I can not reproduce this locally, so it may be because of some rustc version or something else entirely

[ten3roberts]

Ok, I've now found the reason for failure.

It has do to with rustc versions. 1.65 causes it to fail, 1.71 passes

[ten3roberts]

As I suspected, "updating" the "minimal_features" backtrace to match caused other tests using 1.75.0 to fail, since somewhere between those versions, the functions and call stack of the panic machinery changed which causes them to match.

The solution I see here is to ignore the tests for the older version, or don't test backtraces on older compiler versions.

[ten3roberts]

Found a common denominator and a way to make the tests more lenient in the future.

Really good work on the UI tests, those were tough.

I posed a few questions, but the core of it looks ready to me.

[thenorili]

How does changing to "--no-default-features" for eyre's track-caller and auto-install tests relate to adding color-eyre to the workspace?

[ten3roberts]

Not sure, I think it was Pavan who added that to increase the test coverage for feature combinations. This is one of the earliest commits

[thenorili]

Well, it's replacing two feature combinations, i'm not sure that it expands the test coverage. If we want to increase the test coverage we could keep both --features and --no-features.

Remember not to squash this once it's done!

I'm not sure this will be that simple.

How are we going to preserve history when merging color-eyre into eyre? How did y'all do it for spantraces? Does a rebase work? If so, do we need to ping jane for an exception to the policy?

[pksunkara]

Creating a merge commit is enough, isn't it?

I tested it and yes, that is how that works! Sorry for the alarm : )

[ten3roberts]

This works now (barring the conflict), how do we feel about merging this?

[ten3roberts]

I'll make sure to merge it properly into main to preserve the history

[thenorili]

It looks good! Congrats to both of y'all on landing this : )
