Part of #579. A units table in fieldcraft-model: Dimension as SI base exponents, named units with factors (offsets only for absolute °C/°F), unit expressions (t/mm³, W/(m·K)), Quantity kinds with parsing of "210 GPa" / {value, unit} under dimension checks, formatting, and display presets (SI, m-kg-s, mm-t-s-N-MPa, in-lbf-s-psi). Model storage unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UhhZMBTviDQxZvwnyP89fo
