Upload platform-specific release assets for mise compatibility (#4)

* feat: upload platform-specific release assets for mise/ubi support

Upload op-exec as platform-named release assets (linux-amd64, linux-arm64,
darwin-amd64, darwin-arm64) so that mise can install it via the ubi backend
with `mise install ubi:nsheaps/op-exec`.

* fix: resolve shellcheck SC2015 warning in debug function

Replace `A && B || C` pattern with proper if-then-else to avoid
the case where C runs when B fails (even if A is true).

* fix: add mise setup to check workflow for shellcheck and shfmt

The check workflow assumed shellcheck and shfmt were pre-installed on
ubuntu-latest. Add them as mise-managed tools and add a mise setup step
so they are reliably available.
