fix: replace Chiron workaround with complete ephemeris file set

Replace custom seas_18.se1 workaround (223KB) with the full set of
time-segmented Swiss Ephemeris asteroid files needed for Chiron
positions from ~675 CE to ~4650 CE and beyond.

- 28 seas_*.se1 files (Chiron time segments from seas_00 to seas_168)
- 10 sepl_*.se1 files (far-future planetary/moon segments)
- 10 semo_*.se1 files (far-future moon segments)
- All sourced from Swiss Ephemeris DE441 distribution

Trump Chiron verified: Libra 14.91 (matches expected Libra 14°54)
