The pinned proxy map dropped urllib's REQUEST_METHOD rule: in a CGI process
an uppercase HTTP_PROXY can come from a client's Proxy header, and AMP's
login and deployment ZIPs would follow it. REQUEST_METHOD is now pinned with
the other transport variables, and the map is read exactly as urllib reads it.
The JSON-crew runner skipped any ImportError from crewai_core.plus_api. It now
skips only a crewai-core too old to have the module; any other failure stops
the run with its own error instead of running with nothing pinned.
