fix(evm): clone query cosmos proto buffers

[beer-1]

Description

Closes: N/A

This fixes a data race in the query_cosmos precompile by treating whitelist protobuf messages as prototypes only. The precompile now clones request and response messages before JSON/protobuf conversion so concurrent calls do not mutate shared decode buffers.

The PR also adds concurrent regression coverage for query_cosmos using a shared whitelist and independent precompile instances. The test asserts zero errors and zero mismatched query results.

Walkthrough

In ExtendedRun's METHOD_QUERY_COSMOS path, protoSet.Request and protoSet.Response are now cloned via proto.Clone before each JSON↔proto conversion. A new concurrent stress test Test_QueryCosmosDataRace validates the fix by running many parallel precompile calls and asserting zero mismatches or errors.

Changes

Cosmos Query Proto Clone Fix

Layer / File(s)	Summary
Clone proto templates in METHOD_QUERY_COSMOS x/evm/precompiles/cosmos/contract.go	Adds github.com/cosmos/gogoproto/proto import; replaces direct use of protoSet.Request and protoSet.Response with proto.Clone copies at lines 341 and 354 to isolate each concurrent call from the shared template.
Concurrent data-race stress test x/evm/precompiles/cosmos/contract_test.go	Adds sync/sync/atomic imports and Test_QueryCosmosDataRace, which spawns a large goroutine pool running ExtendedRun concurrently against a mocked gRPC router, collecting panics, errors, and response-field mismatches atomically before asserting all counts are zero.

Poem

🐇 Two little templates once shared without care,
Goroutines would scramble and mangle the pair.
Now Clone makes a copy for each little call,
No race, no corruption — no chaos at all!
The rabbit hops safely through concurrent land. 🌟
