fix(git-hooks): replace GNU-only sort -V with portable zero-pad sort

sort -V is a GNU extension; BSD sort on macOS does not support it. When
node is absent from PATH and the nvm fallback runs, set -euo pipefail
causes the unsupported flag to abort the hook before lint/format can
run, blocking commits on macOS.

Replace the sort -V | tail -1 pipeline with a Bash for-loop that
zero-pads each semver component to five digits and emits a tab-delimited
key+path line. Plain sort + tail -1 + cut then selects the highest
semantic version — no GNU-only flags required.

Smoke-tested with v18 vs v22 paths; v22 is correctly selected on both
GNU and BSD sort.
