Flag to ignore secret rather than ECONNRESET

Would you be open to a PR that adds a flag to make the proxy ignore secrets for non-allowed hosts rather than terminating the connection?

Termination makes sense for making the user aware "something bad" might be happening.

But we're finding lots of trouble with the AI agent reading scripts and things that reference the secret variable names, those end up in the agent context, then all agent API requests end up in ECONNRESET.

Maybe a flag disabling ECONNRESET for a particular host?
