docs: bring the README layout and the branch claim back to the code

README described a three-skill plugin that ships six. skills/page and
skills/wiki were absent from What it ships and from the project tree, so
/tea:page and /tea:wiki could not be discovered from the front page at
all; labels.py, close.py, evict.py, issue_evict.py, pin.py and the
agents-sync hook were missing from the tree too. Layout now matches
AGENTS.md, and says which of the two is authoritative.

The sync skill promised that push writes the computed branch back into
the issue file. It cannot: a successful push deletes the file, which
push.py:260-271 and its docstring already said. The paragraph now says
what happens instead — the ref goes up, and the branch comes back on the
next pull, from the tracker. The three claims around it were correct and
are kept.

Closes #27
Closes #31
