Automates the manual merge step from README.md section 1: regenerates
sym-lib-table.global/fp-lib-table.global from the project tables, then
adds any MIKILAB_* entries missing from KiCad's installed global tables
(~/Library/Preferences/kicad/10.0/), leaving every other entry
untouched and backing up both files first. Refuses to run while KiCad
is open, since it would otherwise overwrite the merge with its
in-memory copy on exit.
