jkomyno b11f31cec8 fix(installer): satisfy shellcheck in install.sh and the shell variants ...

The Install Script Unit Tests job runs `shellcheck -s sh install.sh
install/*.sh`, which exits non-zero on any finding including info-level
ones. Four SC2015 diagnostics ("A && B || C is not if-then-else") failed
the job on next, which also skipped the Test Install Script legs that
depend on it.

Rewrite both patterns as explicit conditionals. Behavior is unchanged:
debug() still prints only when COMPOSIO_DEBUG is truthy and still
returns 0 otherwise, and the release-metadata guard still aborts when
either field is empty.
