Bring the figures the comments quote back to what the catalogue now holds

Later commits on this branch (0e9ab6f, ff744a0, 8c3a860, and this round's fold, positional lookup
and parallax fallback) changed counts that comments in build.ts, star-readouts.ts, star-catalog.ts
and fetchExoplanets.ts still quoted as "measured" or "today". Each is now the value measured on the
published catalogue after an ETL run from cache (decoded with decodeStarCatalog, or from the
validator log where it prints them):

- distances without a published error 439 -> 346, the Gliese ones 357 -> 264 (82 archive);
- parallax distances ranged 1 109 -> 1 116; HYG stars at Gaia's distance 8 129 -> 8 105, and the
  Gaia-placed stars HYG describes 62 002 -> 61 713 at Gaia's distance, 62 097 in all;
- HYG rows without a Gaia counterpart 11 554 -> 11 478: past 250 pc 8 307 (1 660 naked-eye), inside
  it 3 170 (1 204 brighter than V 8, 1 804 from 8 to 12, 162 fainter, 112 of them Gliese stars
  within 50 pc); the sentence also said those were every star past 250 pc, which the archive's
  hosts no longer let it be;
- planets with a host 6 327 -> 6 328, the 26 left having neither a distance nor a parallax;
- renamed hosts 575 -> 574; the composite table fills 100 of the 127 blank distances, not "the 100".

No ceiling or floor changes; comments only.
