fix: reconnect-on-stale re-selects folder; lock connect() against races

ensure_connection() reconnected via connect(), which only reaches IMAP
state AUTH, not SELECTED - every search/fetch/store after a mid-pass
link drop silently failed (swallowed into []/None/False) because
aioimaplib rejects those commands outside SELECTED. Track the
currently-selected folder and re-select it after reconnecting; note
pre-reconnect sequence-number ids are invalid post-reconnect unless
use_uid=True.

Also add an asyncio.Lock around connect()/close()/ensure_connection():
concurrent callers on one instance used to race inside connect(),
where task B's `await self.close()` tore down task A's mid-handshake
connection, leaking sockets and orphaning server sessions. Superseded
connections are now always logged out instead of silently overwritten.

Bump to 0.1.6, update README install pins.
