meta: deprecate @urbit/api

[tomholford]

This is a tangential task to an ongoing effort to implement Userspace Permissions UI (tloncorp/landscape#182)

As a prerequisite for UP: the npm SDK which frontend developers use for integrating with Landscape APIs needs to be updated with interfaces for the new pokes and scries.

Previously, this would be @urbit/api. However, per this PR the package is now deprecated: urbit/urbit#6232

Tlon has long had plans to release a successor to Indigo 1. The vision at this point is to create a new @tloncorp/gear package which will provide types for integrating with Landscape, as well as a component library and useful hooks for querying and managing state.

So why this PR: Since the new package will not have the Webterm types and utility functions, will migrate them from the deprecated package to this repo (See: tloncorp/landscape#176)

lgtm, may want to double check @urbit/aura has a peer dep of big-integer that I don't see here

[tomholford]

Confirmed that npm does not detect any missing peer deps:

If you want to check for missing peer dependencies manually, you can use the npm ls command. This will print out your dependency tree along with any issues it detects, including missing peer dependencies.
