Subject: [PATCH] balance: increase runestone yield 50% per prestige (#166)

Raise runestonesPerPrestigeLevel from 10 to 15. Early-game players
were earning only 10-20 runestones per prestige, making the upgrade
shop feel out of reach. This boost helps mid-game without affecting
the cap behaviour (cbrt formula still prevents AFK windfalls).
