Subject: [PATCH] refactor(state-machine): derive legend from the machine's
 edges
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add navigate/changeScope transition kinds and build the legend from the
transitions a machine actually has, so each blueprint shows only its own
kinds — needed for Calendar, whose lifecycle has no loadMore().
