v0.23.2

Fixed

• Resolve thousands grouping and decimal commas in the lexer before a successfully parsed expression can return a silently wrong result. Support mixed decimal/grouping conventions, Swiss apostrophes, and Indian grouping while retaining function argument commas and numeric-date parsing.
• Preserve measured values with absolute uncertainty (12,3 ± 4,5) and German million/billion abbreviations (1,08 Mrd. km/h).
• Compare compact competitor result displays such as 300k numerically and retain the participant-count unit in the corpus expectation.
• Preserve space-grouped fractions and underscore/space grouping, parse radix literals numerically, and report scale overflow without panicking. Document the required fend 1,1 compatibility exception.
• Reject unsupported compound-unit powers, functions, and mixed-unit algebra instead of silently discarding their units.
