Replacing the Static Global Map with a Dynamic "Expedition" System

The current map is static, lacks events, and becomes obsolete after first use, failing to engage players long-term.
Implement a repeatable, procedurally-generated Expedition system where players deploy their ship to uncharted sectors. Each mission features a unique map with scaling length, hazards, enemies, and rewards based on difficulty. Expeditions provide valuable loot, including resources, settlement and mining coordinates, and exclusive blueprints.
Benefits:
- Endless Replayability: Procedural generation ensures infinite fresh content.
- Sustainable Economy: A reliable source of resources and credits, solving late-game scarcity.
- Constant Engagement: A rewarding core loop for both short and long play sessions.
This shift creates a compelling, evergreen gameplay loop that leverages roguelike strengths, significantly enhancing the game's longevity.
