Subject: [PATCH] feat(host-factory): register ChunkRenderer + PayloadHandler +
 Lender (F)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F adds the 3 new DI registrations needed for the v1.7.1 R-Block:

- ChunkRenderer (4-param ctor: themes, fonts, logger, gameFunctions)
- PayloadHandler singleton (7-param ctor: themes, ipc, functions,
  inputBar, mainWindow, chunkRenderer, logger)
- Lender<PayloadHandler> factory (closure over sp, constructs a fresh
  PayloadHandler per Borrow() — used by InputPreview in Sub-Task I)

All three use Factory-Lambdas because Lender<T> has an internal ctor and
ChunkRenderer/PayloadHandler are internal sealed (ActivatorUtilities
can't reflect into internal ctors per [[reference_hellion_chat_di_container_v150]]).

MainWindow DI-reg update is deferred to Sub-Task A2 (split per Flo
2026-05-27 to avoid the DI-cycle that would otherwise emerge from the
PayloadHandler → MainWindow → MessageList → PayloadHandler graph —
cycle resolved via setter-injection on MessageList in G/H).

G is next: wires PayloadHandlerInitHostedService.StartAsync to register
the AddonLifecycle listener for MoveTooltip and call MessageList.
AttachPayloadHandler. H adds the MessageList ChunkRenderer ctor-param +
AttachPayloadHandler setter.
