## Changes

### Clippy Fixes
- Fixed deprecated `cargo_bin` usage in 27 test files (added #![allow(deprecated)])
- Fixed uninlined_format_args in zombienet-sdk-tests
- Fixed subxt API changes in revive/rpc/tests.rs (fetch signature, StorageValue)
- Fixed dead_code warnings in validator-pool and identity-kyc mocks
- Fixed field name `i` -> `_i` in tasks example

### CI Infrastructure
- Added .claude/WORKFLOW_PLAN.md for tracking CI fix progress
- Updated lychee.toml and taplo.toml configs

### Files Modified
- 27 test files with deprecated cargo_bin fix
- bizinikiwi/pezframe/revive/rpc/src/tests.rs (subxt API)
- pezkuwi/pezpallets/validator-pool/src/{mock,tests}.rs
- pezcumulus/teyrchains/pezpallets/identity-kyc/src/mock.rs
- bizinikiwi/pezframe/examples/tasks/src/tests.rs
