Ryan Malloy 747b7ae60a Fix L1 inclination pruning for HEO orbits, add 66k benchmark ...

Bug: inner_consistent used sma_low for footprint calculation, but
ground footprint grows with altitude. High-SMA bins (GTO, HEO)
need sma_high to compute the maximum footprint — using sma_low
caused 453 false negatives at high-latitude observers (Tromsoe).

Fix: use sma_high (not sma_low) in L1 inclination pruning.

Added regression test: GTO-debris (inc 5 deg, e=0.73) at Tromsoe
must return identical results from seqscan and index scan.

Benchmark on 65,886-object catalog (full Space-Track including
decayed): 80-92% pruning, zero false negatives across 7 query
patterns. SP-GiST beats seqscan for high-latitude observers.
