Subject: [PATCH] fix: scale tiers 11-16 upgrade costs and reorder
 arcane_scholar_1 (#113, #114)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tiers 11-16 had essence costs of 150-2000 — far too low compared to
tier 10 (500K gold) and tier 17 (10M essence), creating a 5000x jump.

New costs scale ~5x per tier to bridge the gap:
  arcane_scholar_1 (tier 11): 150 → 1,000 essence
  shadow_assassin_1 (tier 12): 175 → 5,000 essence
  dark_templar_1 (tier 13): 200 → 25,000 essence
  void_walker_1 (tier 14): 300 → 100,000 essence
  celestial_guard_1 (tier 15): 750 → 500,000 essence
  divine_champion_1 (tier 16): 2,000 → 2,000,000 essence

Also reordered arcane_scholar_1 (tier 11) before shadow_assassin_1
(tier 12) to match ascending tier order in the file.
