fix(content): correct Golestan topology wording to match 2-aperture data

GJ 680 has aperture_count=2 / gate_connections=2, linking two distinct
systems (Athabasca GJ 1289 and Enugu GJ 75) — but the prose, inherited
verbatim from the original Carnarvon page, described "one gate in, one
gate out, both the same gate" and "one aperture connecting to Enugu and
Athabasca" (self-contradictory). Reword the gttr and index to two gates
while keeping the system's low-through-traffic spur character (the
spur_end topology label and "nobody routes through here" identity are
unchanged). Resolves the deferred PR #146 review finding.

 ## The Spur
 
-One gate in, one gate out — both the same gate. No through traffic. Everything that passes through Golestan's horizon station is either coming here or came from here. The economy is correspondingly local: mixed cereal and legume agriculture on the primary, light manufacturing for self-maintenance, and a fishing cooperative on the second-largest settlement body that has been running on the same structure for three hundred years. The Farahani family arrived on a wave_2 land-survey contract four centuries ago and simply stayed when the survey was complete. The family name appears on four of the seven primary agricultural regions and two of the manufacturing cooperatives. The land was surveyed by the Farahanis, allocated by the Farahanis, and has passed to Farahani descendants in every generation since. The Assembly's inheritance and land-use frameworks nominally apply. No one has ever tested them here.
+Two gates — one toward Athabasca, one toward Enugu — and next to no through traffic on either: nobody routes through Golestan who isn't bound for it.

 The Persian-heritage founding culture — an old landed sensibility, patient and proprietary, deeply skeptical of external institutional claims on what a family has held and worked for four centuries — makes Golestan more comfortable with its effective isolation than most Assembly administrators would prefer. The system is not hostile to outside contact. It simply does not require it.

 ## Practical Information
 
-Golestan is six hops from Gateway with one aperture connecting to Enugu and Athabasca. The K5 primary is warm and steady by outer arc standards. The fishing cooperative produces a surplus of processed marine protein. The agricultural governance council is slow, consensual, and weighted in practice by vote blocs that formal structures would officially decline to acknowledge. Assembly's nearest outpost is at Athabasca. Gate Corp maintains a minimal rotating crew.

 Nobody comes here without a purpose. The Farahanis are hospitable to people with purposes.

 ## Supply Dependency
 
-Golestan is a spur, which shapes everything about it. One gate in, one gate out — both the same gate. The horizon station connects back toward Athabasca and Enugu, but there is no through traffic, no corridor of systems depending on Golestan as a waypoint. What passes through the gate is either coming here or came from here. The economy is correspondingly local: mixed cereal and legume agriculture on the primary, light manufacturing that supplies its own maintenance, and a fishing industry on the second-largest settlement body that has been running on the same cooperative structure for three hundred years.

 The Farahani family — Persian-heritage founders who arrived on a wave_2 land-survey contract and simply stayed when the survey was complete — remain the system's largest agricultural landholders. The family name appears on four of the seven primary agricultural regions and two of the manufacturing cooperatives. This is not unusual for a spur-end system with four centuries of continuous settlement and no demographic disruption. The land was surveyed by the Farahanis, allocated by the Farahanis, and has passed to Farahani descendants in every generation since. The Assembly's inheritance and land-use frameworks nominally apply. No one has ever tested them here.
