astra: megastructure launch infrastructure — docs, claims, and review fixes
- Added megastructure launch infrastructure to world model (identity.md),
new belief #7 (beliefs.md), viability assessment framework (reasoning.md),
and new domain map section (_map.md)
- Added 3 speculative claims: skyhooks (momentum exchange), Lofstrom loops
(propellant-to-electricity transition), bootstrapping sequence economics
- Belief #7 grounded on new megastructure claims (not chemical rocket claims)
- Confidence calibration: speculative content flagged as theoretical/unprototyped
- Propellant depot complementarity: megastructures for Earth-to-orbit, depots
for in-space operations — complementary not competitive
- Clarified economic vs technological bootstrapping distinction
- Added power constraint wiki-link to megastructure sections
- 300km tether contextualized relative to 35,786km space elevator
