v0.5.0

What's new

• Starting Map option — choose between Moorland Trenches, Keepsake Bay (default), or Old Fort Creek
• Co-op support — 2 players sharing the same AP slot via RWR's native LAN/Internet co-op. Guest character is auto-synced to the current AP rank on join
• Periodic rank sync — clamps XP to the AP rank threshold every 15s (prevents drift from kills or natural XP gain)
• Lower RP Shop default cost — 1000 → 500 RP per check
