Add knight health, boss attack patterns, chases, and music

Knight now has a hit-bar (pirates deal 1, bosses deal 3 damage) with
a new vitality upgrade. Bosses grow bigger/scarier and cycle through
melee/missile/bomb/laser attack patterns; boss HP is now exactly 3x
the local pirate's. Zones 20 and 40 replace their boss with a unique
chase (Pirate Cruiser laser dodge + fuel cell collection; Black Swarm
plasma dodge with a tap-to-escape engulf event). Pirates spawn 5x
faster and got a bandana/eyepatch redesign. Added a procedural music
engine, a visible destination galaxy in the supernova cutscene, and
expanded the Data Archive lore to trigger at zones 10/20/40/60/80/100.
