Problem

--assignee self fails with:

Could not determine user ID for assignee self

Root Cause

The code in issue-create.ts uses "self" as the keyword for auto-assigning to the current user (lines 184, 389, 648), but lookupUserId() only checks for "@me".

When "self" is passed, it falls through to the user search query which looks for a user literally named "self" - which doesn't exist.

Fix

Add "self" as an alias alongside "@me" in lookupUserId():

if (input === "@me" || input === "self") {

Now both --assignee self and --assignee @me work correctly.
