Bug: Expose types in CodebuffClientOptions

[dannyighsu]

CodebuffClientOptions is exposed publicly but these types in the signature are not. This is helpful for strongly typing tool overrides, among other things:

export function changeFile(
  parameters: unknown,
  cwd: string,
): CodebuffToolOutput<'str_replace'> { ... }

Awesome! Great change. I just exposed ToolName instead of PublishedToolName, but will merge now!
