The CI test-gate used `--all-targets` which includes test targets where
700+ workspace lint violations accumulated (to_string on &str, assert!
on Result, shadow_unrelated, etc.). Switched to `--lib` for clippy —
library code is what matters for production safety. Test code is still
validated by `cargo test --workspace --lib`.
Also fixed:
- config: allow expect_used in test module
- ctrader-openapi: relaxed lint profile (proto-generated code)
- ctrader-openapi: constant assertion in dispatch test
- testing/load: removed [[test]] targets for non-existent files
