21			Resolver Frontend
22			=================
23
24			This file implements the public resolver class, which delegates to
25			platform-specific services:
26			- Windows: win_resolver_service (uses GetAddrInfoExW)
27			- POSIX: posix_resolver_service (uses getaddrinfo + worker threads)
28
29			The resolver constructor uses find_service() to locate the resolver
30			service, which must have been previously created by the scheduler
31			during io_context construction. If not found, construction fails.
32
33			This separation allows the public API to be platform-agnostic while
34			the implementation details are hidden in the detail namespace.
