Peritheos 0.17.2

Added

• Add the published Prescher (2012) Fe3C full-range BM3 parameterization,
  preserving K0=161 +/-2 GPa and K0-prime=5.9 +/-0.2. Identify the adopted,
  fixed curve-derived V0=154.5678863704812 A^3 separately from a published
  coefficient or ambient measurement.
• Make the complete numbered p1-p19 Table S1 series with published ruby
  pressures the primary dataset. Retain the 22 digitized Figure 1 markers
  separately, with source coordinate widths, raw tokens and recovery evidence.
• Document conditional central-coefficient parity and the remaining K0 error
  mismatch: the 19-point fixed-V0 comparison gives 160.994011 +/-2.532193 GPa,
  displayed as 161 +/-3 at the paper precision rather than the published 161 +/-2.
  Original source confidence, weights and the author V0 constraint remain unknown.
  Split fits stay audit-only; no additional EOS choice or new default is introduced.

Compatibility and scientific limits

• Preserve explicitly audited paper precision in repository report comparisons;
  the optional display setting leaves stored coefficients, errors and default
  rounding unchanged.
• Preserve all 678 other released EOS source records and scientific model code.
  The catalog contains 233 materials and 679 EOS records. Numerical agreement
  does not establish author-workflow reproduction or physical validation.
