Sergio Chouhy 50be74580b refactor!: move LEZ related crates to dedicated directory 
BREAKING CHANGE: LEZ crates have been moved from top-level directories into
  a dedicated `lez/` subdirectory. The following crates were relocated:

    common          → lez/common
    indexer         → lez/indexer
    explorer_service→ lez/explorer_service
    keycard_wallet  → lez/keycard_wallet
    mempool         → lez/mempool
    sequencer       → lez/sequencer
    storage         → lez/storage
    testnet_initial_state → lez/testnet_initial_state
    wallet          → lez/wallet
    wallet-ffi      → lez/wallet-ffi

  Any external tooling, scripts, or paths referencing these crates at their
  previous top-level locations must be updated.
