The contributor bootstrap script was bash-only ('#!/usr/bin/env bash',
'set -euo pipefail', '[[ ... == ... ]]') while install.sh and
uninstall.sh are POSIX sh. Consistency lines them up:
- shebang -> '#!/usr/bin/env sh'
- 'set -euo pipefail' -> 'set -eu' (pipefail isn't POSIX; not needed
here either, no risky pipelines in this script)
- '[[ ... == ... ]]' -> '[ ... = ... ]'
Also added a 'bun run test' hint to the post-install workflow note now
that there's a test suite to run.
