Function drop_token_cache 

pub fn drop_token_cache()

Public variant used by callers that mutated auth.toml out-of-band (e.g. the TUI’s auth ops spawn a child process via torii auth oauth … — the child invalidates its own cache when it calls set_token, but the parent TUI has no way of knowing that without an explicit cue). Call this after any operation that could have changed a token outside this process.
