Subject: [PATCH] install.sh: after install, clear stale command hash + print
 'hash -r' hint

A bash shell may still hash pmm to an old (now-deleted) path such as
~/.pmm/root/bin/pmm, so running pmm after a fresh install fails with
'No such file or directory' until 'hash -r'. Install scripts run in a
subshell and cannot clear the interactive shell's hash, so run hash -r
best-effort and print an explicit 'hash -r (zsh: rehash)' instruction.
