Subject: [PATCH] Joinery list: show what each feature connects to (not just
 "connected")
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The connected indicator now reads "🔗 → <board>" naming the mating board, so a
part legitimately in two connections shows each feature's distinct mate, and a
free feature shows nothing. (A connection always links two features on two
different boards, so a board showing both features connected means it's in two
connections — verified the model never over-marks from a single connect.)

86 tests pass.
