plus fix ci tests (reading stdin is weird in ci - isTerminal fails fails even though nothing is piped through it)

couple of caveats:

• skipping tests not via stdin because ci is weird (detecting it and skipping the test)
• overriding cargo tests to never trigger stdin reads (broken on ci in similar vein)
• skipping windows direct use of < operator in tests (yq '.[2].metadata' < test/deploy.yaml gave The '<' operator is reserved for future use.)
• skipping windows direct use of evars (The term 'RUST_LOG=debug' is not recognized as a name of a cmdlet, function, script file, or executable program.)
