Walkthrough

This pull request removes the Wasmd precompile feature entirely from the codebase. The changes include deletion of the Solidity interface (IWasmd.sol), all Go implementation files in precompiles/wasmd (including event emission, transaction handling, query methods, and types), corresponding unit and integration tests, mock contract bindings, and E2E test files. A new v7.1.0 upgrade handler is added that filters the Wasmd precompile address (0x0000000000000000000000000000000000001001) from the EVM's active static precompiles list. The precompile registration is removed from app/keepers/precompiles.go, and genesis configurations are updated accordingly. The changelog documents the removal.
