fix: comprehensive feature propagation and dep:serde fixes

- Fix serde optional dependency issues by adding dep:serde to serde features (24 crates)
- Run zepter to propagate runtime-benchmarks, std, try-runtime, serde, experimental, with-tracing, tuples-96 features
- Regenerate umbrella crate with proper feature propagation
- Format all TOML files with taplo

This resolves check-umbrella and check-zepter CI failures.
