Add `@deprecated` tag to legacy `.forge` interface?

[achingbrain]

According to the readme the .forge sub-API is deprecated and will be removed in a future major of acme-client.

I only discovered this when someone else pointed it out during code review. If you add the @deprecated JSDoc tag to the method along with a description of which API they should use instead, people will see this in their IDE during authoring which will speed adoption of the new API.
