fix(ci): resolve serde_core duplicate alloc in clippy and quick-benchmarks

- Exclude pezkuwi-zombienet-sdk-tests from clippy (nested cargo build
  in build.rs overrides SKIP_WASM_BUILD with empty string, triggering
  wasm32-unknown-unknown + build-std which conflicts with serde_core)
- Use WASM_BUILD_STD=0 for quick-benchmarks to avoid build-std
  (uses pre-built wasm32-unknown-unknown sysroot instead)
- Update CLAUDE.md with correct CI runner VPS info
