Behaviour graph: a node canvas replaces the rule list

-Under the moves are the rules (`[[rule]]`), each read as a sentence ("after the lunge for 20
-frames, within 1200, play stamp"): New rule plays the picked move once when the monster notices

+The Behaviour tab edits the port's `[behaviour]` as rules, grouped by what starts them: an event, a
+state between moves, or a move playing. The game checks rules in rank order, `#1` first. Rank is the
+stored canvas order, each block's `(y, x)`, top first: `+ Rule` adds a rule last, dragging a rule's
+frame trades places with its own trigger's rules only, and in All rules › Canvas dragging a node can
+change it. In Canvas a block's `out` wires to the next block's `in` or to a move's `play`; a move's
+`while playing` starts a rule, and `then` sets the move's `after`. The palette is
+`mhfu_port.behaviour.KINDS`. Watch the game, in the header, reads the running game once a second
+while the tab is shown and marks each frame and trigger with how often the game fired its rules
+(`7×`; a frame lights up when its count rises): the game must run this port's rules as Play in game
+sends them, and the header says when it does not. The tab keeps its own docks; Findings stays open
+across tabs.
