fix(install): read from /dev/tty so curl | bash confirmation prompt works, bump v0.5.2

set -euo pipefail causes the script to exit when read gets EOF from
the curl pipe instead of an interactive terminal. Fix by appending
'< /dev/tty || CONFIRM=Y' so the prompt reads from the actual terminal
regardless of how the script was invoked.
