v0.0.13

Added

• Minor bodies: Ceres, Pallas, Juno, Vesta, Astraea, Eris, Sedna, Makemake, Orcus and Ixion
  in every chart (after Lilith, before the angles), from embedded tables sampled from JPL
  Horizons for 1849-2151 (within 3″ of it; outside, unavailable_bodies). They form
  aspects within their own orb (default 3°, whatever the orb method) but none with each
  other, and take no part in fixed-star conjunctions or the temperament.
  MINOR_BODIES / is_minor_body are public, and MINOR_BODIES is exported to Python.
• Python: Engine.chinese_calendar(moment), excerpt_kernel(path, start, end),
  election(chinese_calendar=), and every exception carries the API error code in .code.
  WASM: Engine.chineseCalendar(utc) and an Engine.kernels getter.

Changed

• About 3× faster charts from file-backed kernels (cached kernel reads, one nutation per
  chart); outputs are bit-identical.
• time_lords returns Result<TimeLords, EngineError>.

Fixed

• Corrupt or hostile kernels can no longer request huge buffers or overflow addresses;
  kernels whose bodies are split into several time segments use the segment covering the
  date.
• Nonsensical input (latitudes beyond ±90°, non-finite numbers and orbs, impossible dates,
  a quesited house outside 1-12) is rejected as invalid_input instead of computed.
• Election searches confirm each window on exact positions before counting it.
