Environments beta feedback: op with environments takes 30+ seconds

Hi, just some feedback on the environments beta (which is great and exactly what we need for our use case).

`op environment read` takes over 30 seconds to complete on my macos system, but takes 1.5 seconds when run in service account token mode (with OP_SERVICE_ACCOUNT_TOKEN). 

This makes `op` with the desktop app connection unusable for our use case: I was using op in a distributed mcp server startup script. the mcp server never stayed running for long; the reason was that `op environment read` taking as long as it did hit the mcp server startup timeout. 

Thanks!
