arithma 0.3.0

174 tools across 23 categories. Highlights:

Features

• power: accepts fractional and negative exponents (2^0.5, 2^-3)
• scientific.factorial: raised to 1000 via BigUint
• listToolCategories: new tool enumerating tool-module categories
• molarMass: Uuo/Uut/Uup/Uus/Uuq/Uuh aliases for pre-2016 IUPAC names
• DATA_STORAGE: B alias for byte
• convertTimezone: DST-strict (rejects spring-forward gaps / fall-back folds)

Fixes

• urlDecode: + decodes to space per form-encoding
• amortizationSchedule: 480-month cap fits MCP token budget
• kinematics: BigDecimal path avoids f64 fma drift
• polarToRect: 15-sig-digit snap at notable angles
• expandIpv6: dotted IPv4 for v4-mapped addresses
• gaussianElimination: inconsistent vs underdetermined distinction
• primeFactors(1): empty product (no longer an error)
• derivative/plot/solve/findRoots: clearer UNKNOWN_VARIABLE envelope
• cooking gas mark error: canonical envelope shape
• digital_electronics.timer555: precision-preserving period formula
• geometry/statistics/vector: overflow guard funnels ±∞/NaN
