#4632 Find a working-directory Swamp repo even with `SWAMP_SERVE_URL` in the environment

Problem Statement

I would like to be able to set SWAMP_SERVE_URL permanently in the environment to allow all sorts of source repositories to take advantage of the software factory being served there.

Yet many of those repositories also have their own Swamp repos with their own behaviors, etc. I want to use those, too!

Proposed Solution

This is tricky because there are 1,001 ways this could go sideways but I would like Swamp to look for behaviors, etc. in the local Swamp repo and then at the SWAMP_SERVE_URL.

It seems only fair to contemplate including SWAMP_REPO_DIR in this treatment, too, and it appears to already take precedence over the current working directory.

Alternatives Considered

It seems much more complicated and confusing, too, to attempt to merge the two Swamp repos ad-hoc.

But the main alternative is simply to not set either environment variable and always mind my working directory and --server ... option.
