Add planet conquest state and gate extractor placement (#41)

Browse source 
Planets now need every capture point held before an extractor can go
up there: GameState tracks per-planet capture progress keyed by the
same stable planet_id as extractors, and BuildController's four
extractor placement checks (menu enable, status text, info popup,
confirm) all re-check conquest, not just proximity/duplication.

Part of the #40 conquest-mechanic breakdown.
