Resolves#1041
## Description:
Remove the singleplayer spawn countdown so the game starts when the
player spawns, spawn nations immediately after player spawn, and align
game timer/max-timer timing with the new start point.
Added a singleplayer regression test for spawn-immunity timing
(GameImpl.test.ts) and updated spawn-phase loop tests to use gameType:
GameType.Public where singleplayer behavior is not under test (e.g.
MIRV/AI/Spawn/WinCheck-related suites), eliminating inSpawnPhase()
timeout hangs after the new singleplayer start logic.

## Description:
### SAM Overwhelming (`NationNukeBehavior.ts`)
On Impossible difficulty, nations can now destroy enemy SAMs by
overwhelming them with coordinated atom bomb salvos. When no good nuke
target is found (all trajectories intercepted by SAMs), the nations
will:
- Identify the easiest enemy SAM to destroy (lowest level first)
- Calculate the total interception capacity of all covering SAMs and
send enough bombs to overwhelm them (+1 extra per 5 needed to account
for enemy building more SAMs during flight)
- Plan launches in NukeExecution's Manhattan-distance silo order,
tracking which silos have interceptable trajectories (wasted bombs)
- Use a sliding window over parabolic flight times to find the best
cluster of bombs that can arrive within half the SAM cooldown window
- Compute per-bomb wait ticks to synchronize arrivals from silos at
different distances
- Skip launching if a salvo is already in flight
- Upgrade the best SAM-protected silo when silo capacity is
insufficient; wait and save gold when only gold is lacking

### 2-Player Endgame Handling (`NationNukeBehavior.ts`)
- On Hard/Impossible with only 2 players remaining,
`findBestNukeTarget()` directly targets the other player (bypasses all
priority logic)
- `getPerceivedNukeCost()` returns actual cost (no MIRV saving
inflation) when only 2 players are left
### SAM Build Rate (`NationStructureBehavior.ts`)
- Reduced SAM perceived cost increase per owned from 1.0 to 0.5, so
nations build more SAMs
### Island Attack Variety (`AiAttackBehavior.ts`)
- `findNearestIslandEnemy()` now collects up to 2 reachable candidates
and has a 33% chance to pick the second-nearest, adding variety to boat
attack targeting
