feat: #80 + #81 alliances & space program — 13th & 14th abilities (v0.45.0)

#80: TurnResult.alliances — form/break durable mutual-defense pacts (GameState.alliances; pair relation → ally/neutral, an active war overrides).
#81: TurnResult.space — launch/deorbit satellites (GameState.satellites; +1 stability per active satellite per turn).
Both appended last to the ABILITIES registry (entries 13 & 14, after contested); durable in SQLite via the stateFields loop, mirrored to regionStats, stats re-derived. System + user prompt goldens updated; 738 unit tests passing.
