feat(query): accept lazy peer.Resolve in query builders

[ernado]

Reworks the peer-resolve ergonomics to match the API in #283 directly, replacing the generated GetHistoryResolve-style helpers merged in #1779.

Before

p, err := peer.Resolve(resolver, "durov")(ctx)
if err != nil {
    // ...
}
query.NewQuery(raw).Messages().GetHistory(p).ForEach(ctx, cb)

After (as per the issue)

query.NewQuery(raw).Messages().GetHistory(peer.Resolve("durov")).ForEach(ctx, cb)

How

• Peer-taking query builders now accept peer.InputPeer instead of tg.InputPeerClass.
  • peer.InputPeer is a small interface (Zero/String) satisfied both by concrete tg.InputPeerClass values and by lazy references, so existing GetHistory(&tg.InputPeerUser{...}) calls keep compiling.
  • tg.InputPeerClass is a sealed interface (unexported construct()), so a lazy type cannot masquerade as one — hence the new interface.
• peer.Resolve(from string) now returns a lazy *peer.Resolved (auto-detecting domain/phone/deeplink). It is resolved inside Query using the builder's resolver, wrapping errors per the repo's context-error semantics.
• The package QueryBuilder carries a peer.Resolver (peer.DefaultResolver by default, overridable via WithResolver).
• peer.ResolveInputPeer(ctx, resolver, input) resolves a peer.InputPeer to a concrete peer; (*Resolved).Bind(resolver) yields a peer.Promise.

Breaking change

peer.Resolve(resolver, from) → peer.Resolve(from). Use peer.Resolve(from).Bind(resolver) for the previous behavior. message.Sender is updated accordingly; peer.ResolveDomain/ResolvePhone/ResolveDeeplink are unchanged.

Generator-only edits

Per CLAUDE.md, only the itergen generator was hand-edited; messages/queries.gen.go is regenerated. make generate is stable.

Testing

• go test -race ./telegram/message/... ./telegram/query/... — green.
• New tests: peer.ResolveInputPeer/Resolved.Bind (concrete, lazy, nil, unsupported paths) and messages query builder with both peer.Resolve(...) and a concrete peer, plus a custom WithResolver.
• Updated ExampleQuery_resolveHistory.
