astra: update domain map with batch 3 governance, stations, market structure

- What: added Space Economy & Market Structure section, expanded Governance with OST/Artemis/resource rights, new cross-domain connections
- Why: 8 new claims need map navigation — space economy baseline, procurement transition, commercial stations, Starship cadence, OST framework, Artemis Accords, resource rights, defense catalyst
- Connections: new links to Hayek, protocol design, good management causes disruption

+The space economy is a $613B commercial industry, not a government-subsidized frontier. Structural shifts in procurement, defense spending, and commercial infrastructure investment are reshaping capital flows.

+- [[the space economy reached 613 billion in 2024 and is converging on 1 trillion by 2032 making it a major global industry not a speculative frontier]] — the baseline: 78% commercial revenue, ground equipment as largest segment

+- [[commercial space stations are the next infrastructure bet as ISS retirement creates a void that 4 companies are racing to fill by 2030]] — the transition: ISS deorbits 2031, marketplace of competing platforms replaces government monument
+- [[defense spending is the new catalyst for space investment with US Space Force budget jumping 39 percent in one year to 40 billion]] — the accelerant: defense demand reshapes VC flows, late-stage deals at decade high
