Subject: [PATCH] feat(io): add Abaqus keyword registration system

New 24-line keyword registration system:
- register_abaqus_keyword(): register keywords for section parsing
- is_abaqus_keyword_registered(): check if keyword is registered
- Global registry for ABAQUS .inp file keywords
- Required by parse_model.jl for section parsing

Provides keyword registration infrastructure for AbaqusReader module.
