GodMacro 0.66.10 — Battleground killing-blow counter

Warcall now uses the same Total Killing Blows API value as MiniKillingBlow's Forever port when it is readable. A stale battleground statistics row or legacy numeric value no longer takes priority over that total.

• Hidden-attacker kill events and later counter updates feed the existing killing-blow voice, banner and attached alerts, with no double counting.
• Reloads, zoning, counter resets and recovery establish a fresh baseline rather than announcing old kills.
• Warcall diagnostics now show the last sampled count as well as the source and confirmed total.
• Existing settings, audio, buffing and all 0.66.9 fixes are preserved. No configuration reset is needed.

This adopts an existing Forever addon method. Event-to-audio behavior is covered by offline regression tests; actual battleground counter updates and audibility still need in-game confirmation. A counter does not reveal the victim or exact rapid-kill timing. No credit is inferred from assists, honor or target deaths.
