stack overflow caused by too long environment resolutions

[h0nIg]

Describe the issue

We build the workspace just using the "prod" groups only. The developers still get the psycopg2-binary / non-prod group by default.

Once too much workspace members have conflict rules (which are resolvable but simply too much exists), the resolution marker probably gets too long. We solved the problem intermediary by shrinking the tool.uv.environments array, but this should still get addressed.
