Lazy-load Intel oneAPI setvars.sh (~1.5s) via wrapper functions that source the environment on first use of icc/icx/ifort/etc. Cache all shell completion outputs to ~/.cache/bash.d/ so they are sourced from disk instead of regenerated via subprocess on every shell start. Cache invalidates automatically when the tool binary is updated. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
