v2.0.0

⚠️ Breaking changes

• PHP 8.5+ is required.
• Dependencies: google/protobuf ^5.36 (was ^3.21), grpc/grpc ^1.82, flexihash/flexihash ^3.0.
• Generated gRPC classes moved from the global namespace to Aternos\Etcd\Proto\…, e.g. \Etcdserverpb\Compare\CompareResult → \Aternos\Etcd\Proto\Etcdserverpb\Compare\CompareResult. The legacy underscore aliases (Compare_CompareResult etc.) were removed.
• get() returns null instead of false for missing keys. The same applies to putIf()/deleteIf() with $returnNewValueOnFail when the key does not exist. Checks like === false must be updated.
• Client constructor: $username/$password are now ?string and default to null (was false).
• Native parameter, return and property types throughout src/. Classes extending the clients or implementing ClientInterface must match the new signatures, and put() now requires a string value.

Fixes

• put() with $prevKv = true no longer crashes when the key didn't exist before.
• getLeaseID(), revokeLeaseID() and refreshLease() now respect the client timeout, so FailoverClient fails over instead of hanging on unresponsive nodes.
• Fixed PHP 8.4 deprecation warnings.

Other changes

• Regenerated the gRPC classes with protoc 36.2.
