feat(chunk-renderer): add skeleton + per-ctor salt + player-hide helpers

Extracts v1.5.6's `ChatLogWindow.HidePlayerInString` / `HashPlayer` into a standalone `Ui/Components/ChunkRenderer` class. C1 lands the skeleton (ctor + DI-deps + salt + two pure helpers); C2 will add DrawChunks/DrawChunk text-path; C3 will add DrawIcon + EmoteCache integration. Salt is per-ctor random matching v1.5.6 session-random behavior — hashed player names change every plugin reload to avoid stable cross-session linkage (Spec §6.5 decision). GameFunctions injected via ctor (not static Plugin.Functions) because Plugin.Functions is a non-static internal property — injection is the correct Components-layer pattern for this dependency. Not yet DI-registered (Sub-Task F) and not yet consumed by MessageList (Sub-Task H) — class compiles standalone.
