fix: resolve pez-kitchensink-runtime compilation errors

Umbrella Crate Fixes:
- Add pezpallet-root-testing to umbrella (std, try-runtime, runtime-full)
- Add pezpallet-xcm-benchmarks to umbrella (std, runtime-benchmarks, runtime-full)
- Add re-exports in umbrella/src/lib.rs for both crates

getrandom WASM Fix:
- Move subxt crates from runtime-full to node feature
- Prevents getrandom dependency leak into WASM builds

Vendor Updates:
- Fix pezkuwi-subxt for web/wasm target compatibility
- Update pezkuwi-zombienet-sdk keystore imports

Documentation:
- Update WORKFLOW_PLAN.md with completed tasks
- Update REBRAND_PROGRESS.md with umbrella fixes
- Remove obsolete tracking files
