🔧 chore(prek): adopt spore-pre-commit formatter

[zrr1999]

Summary

• align the effect-terminology branch with the currently shipped Spore CLI surface
• keep the canonical project-mode example validated in CI
• stop CI from treating the standalone hello example as a compiler-gated check target

Validation

• cargo test --manifest-path host/Cargo.toml
• spore format --check
• find src/basic_cli -name '*.sp' -type f | sort | xargs -n 1 spore check
• spore check examples/hello-app/src/main.sp
• find src/basic_cli -name '*.sp' -type f | sort | xargs -n 1 spore build
• spore build examples/hello-app/src/main.sp
• cd examples/hello-app && spore run src/main.sp
• spore test

Notes

• standalone examples/hello.sp remains as a quick experiment, but it is no longer part of the CI compiler checks
