fix(tools): restore the exec bit on 63 scripts, in the INDEX where it counts

core.fileMode=false means chmod fixes your tree and nothing else — the 203/EXEC
class (log 032) recurs on every fresh checkout because the index said 644.
git update-index --chmod=+x is the repo-level fix; every shebang'd script under
tools/ + gig-up.sh + perf.sh now ships executable.
