Greg Pomerantz 1f5720d7db verify_official: 497/497K forms, per-share layout, candidate re-ranking
- EFTS queries now include 497/497K (many fund families publish their
  per-fund highlights there, not in the consolidated N-CSR) and re-rank
  hits by registrant name match (ticker/brand words), newest first,
  capped at 2 filings per CIK
- new parse_per_share_blocks for the JPMorgan-style 'Per share operating
  performance' table (per-class value blocks; dashes = zero)
- parse_highlights now tolerates row labels split across table cells
  (modernized N-CSRS format, e.g. Calamos 2026)
- region finders: word-flexible name patterns (US vs U.S., class letters),
  self-validating per-share regions (a candidate block must match the
  local series, so a name mention in notes doesn't attribute another
  fund's tables in a combined 58 MB report)
- main() keeps the best result across candidate filings (N-CSRS vs 497
  can round differently) and stops early on 'ok'
- local_series applies the corrections overlay so corrected funds verify
  against their filing

Results: JLPSX and CVSIX now 'ok' (all bounded fiscal years agree with
the official filings); CVSIX also gets a 2023-12-21 0.510 capital-gain
correction. bnd/pmaix still ok (no regression).
