Files to check on Starsector update, because they significantly modify vanilla code that could change under us.
Partial list.

- NexCoreLifecyclePlugin
- NexDeliveryBarEvent
- NexFleetInteractionDialogPluginImpl
- NexFleetEncounterContext
- Nex_MarketCMD
- Nex_SustainedBurnAbilityAI
- SSP_BattleCreationPluginImpl
- InvasionFleetManager.getPatrolCombatFP
- Submarket plugins
- Colony manager: getFreePortGrowthBonus()
- Everything that uses Industries.TAG_UNRAIDABLE

Do on future SS release:
- Remove agent/saboteur commodities
- Remove MutableStatNoFloor
- Add "player colonized" listener
- Nex_BlueprintSwap: Remove starting "$" from POINTS_KEY (it's now a persistent data key, not a memory key)
- Move CeasefirePromptIntel to diplomacy package

Do when handy:
- Refactor: getExerelinFactionConfig() -> getFactionConfig() (deprecate old)
- SectorManager: getHardMode, getCorvusMode -> isHardMode, isCorvusMode (deprecate old)

All files in data.scripts.world.corvus and data.scripts.world.systems should be replaced each Starsector version.
