fix(ci): resolve three pre-existing CI failures (#759)

- Remove unused TerraphimAgent import in multi_agent test (clippy -D warnings)
- Use sh -c instead of sh -lc for workspace hook execution (login shell
  sources /home/alex/tools/rust/cargo/env which doesn't exist on CI runners)
- Add --features zlob to ci-check-format.sh clippy command (fff-search
  build.rs panics in CI without zlob feature enabled)
