E reference docs lack example, link to narrative, appearance in IDE / LSP

in progress; gotta to do a meeting

Describe the bug

When working on an example contract, I hovered over various bits of our API to check whether docs are adequate. E seems to be documented with an elaborate type but no prose / example / links:

Steps to reproduce

1. open packages/far/test/e.test.js in vs-code (or presumably any other editor based on the Language Server Protocol)
2. hover over E
3. see type info but no prose / example

Expected behavior

1. At least these docs should show up:

endo/packages/eventual-send/src/E.js

Lines 193 to 201 in 895ea0a

	/**
	* E(x) returns a proxy on which you can call arbitrary methods. Each of these
	* method calls returns a promise. The method will be invoked on whatever
	* 'x' designates (or resolves to) in a future turn, not this one.
	*
	* @template T
	* @param {T} x target for method/function call
	* @returns {ECallableOrMethods<RemoteFunctions<T>>} method/function call proxy
	*/

Interestingly, they do show up in generated docs:

E | Endo API documentation

2. The reference docs should cite narrative docs: Eventual Send with E()

3. The reference docs should include an example, preferably one that's elaborated on in the narrative docs. E(x).method(...args) is a candidate, though not as
