feat(issue): gh-style issue list, view, create, edit, close and reopen

issue list renders through the shared table: a context line, ID TITLE
LABELS [STATE] [KIND] AUTHOR UPDATED with relative times on a terminal,
the ID colored by state and linked, and a stable tab-separated column
set when piped; empty results say so on stderr. It gains -s -L -l -a -A
-m -S -w, @me, comma-separated label and milestone filters, and --web.

issue view, edit, close and reopen accept #N, OWNER/REPO#N and issue
URLs. Mutations report "✓ Created/Edited/Closed issue alice/x#5 (title)"
on a terminal; issue create prints the new issue's URL on stdout (also
as issue new), and close and reopen skip issues already in that state
with a ! line and take -c/--comment. issue create and edit gain the gh
short flags and singular --add-label, --remove-label, --add-assignee and
--remove-assignee (the plural names still work), and create gains --web.

The interactive create form asks for the title and body, then "What's
next?" (submit, add metadata or cancel), without a confirmation after
it; the edit form names the issue it edits. Every issue command has help
text with examples and completes its flags and issue numbers.
