Bump to 0.5.4: Fix service discovery parameter bug

Bug: getService() was accessing parsed.service (undefined) instead of
parsed.serviceName, causing D1_TYPE_ERROR in service discovery.

This affected both random discovery (line 263) and paginated discovery
(line 218) when clients requested services without specifying username.

The parseServiceFqn() function returns { serviceName, version, username },
not { service, version, username }.

Fixes: D1_TYPE_ERROR: Type 'undefined' not supported for value 'undefined'
when discovering services like 'test-chat:1.0.0' (without @username)
