## Description:
Currently, the game only recorded war gold statistics when a defender
was killed as part of a territory‑annexation sequence. Regular attack
eliminations did not trigger the war gold stat update.
This PR:
- Invokes `stats.goldWar(...)` in the standard elimination code path of
`AttackExecution`, so that any kill - whether by full annexation or
direct attack - correctly increments the attacker's war gold stat.
- A new integration test suite `AttackStats.test.ts` covering both
scenarios
