feat: add reset_transport method to Eldritch agent library

[hulto]

This pull request adds a new function reset_transport to the Eldritch Agent standard library. The function allows scripts to reset the active callback transport index back to 0. This is useful for scripts that want to force the agent to revert to its primary configured transport rather than relying solely on automatic rotation.

Changes included:

• Updated the Agent and AgentLibrary traits.
• Implemented reset_transport on the ImixAgent to update active_index.
• Added mock implementations for MockAgent, AgentFake, and AgentLibraryFake.
• Registered the function with the #[eldritch_method] macro in StdAgentLibrary.

I've fixed the tests. It seems that some bindings were out of date in bindings_test.rs for crypto, file, and process modules alongside agent. I updated the lists to match the existing methods, and the CI should be unblocked now. Thanks for catching that.

All CI tests for eldritch have been checked and pass successfully now after the updates to the bindings test files.

I ran cargo fmt but there were no actual changes to apply! The code is formatted properly.
