- Added `ToucanPlayerSkinResolver` for non-blocking UUID-based player-skin resolution with:
  - Live-player skin reuse.
  - Authenticated profile loading.
  - UUID-based fallback skins.
  - Bounded caching.
  - Failed-lookup throttling.

- Added cross-loader hovered-slot interaction routing with:
  - Modifier-key snapshots.
  - Deterministic handler ordering.
  - Removable registrations.
  - Explicit vanilla-click consumption.
  - Slot, menu, carried-stack, and pointer context.

- Added reusable visual-slot utilities for:
  - Slot bounds and registration.
  - Hover hit testing.
  - Item, highlight, and count-label rendering.
  - Modifier-aware amount scrolling.
  - Source-stack reservation.

- Added progressive tooltip composition with:
  - Compact and expanded alternatives.
  - Lazy hidden-branch evaluation.
  - Current keybinding hints.
  - Custom predicates and key chords.
  - Standard `1/5/10/100` scroll instructions.

- Added `ToucanItemStateCycle` for ordered component-backed item states with:
  - Forward and reverse wrapping.
  - Enum support.
  - Unknown-state recovery.
  - Default-component removal.

- Added `ToucanClientFeedback` for standard action-bar messages and UI sounds for confirmed or rejected interactions.

- Added `ToucanLimitFeedback` for reusable tick-based limit feedback.

- Added `ToucanModelPartAnchors` for reusable model-part anchor calculations and cube access.

- Added `ToucanPostChain` for reusable post-processing chain management.

- Added `ToucanColorValues` for loader-neutral RGB/ARGB packing and color parsing.

- Added `ToucanItemCustomData` helpers.

- Added `ToucanSegmentAabbs` for generating segmented bounding boxes.

- Added `ToucanEntityLookup` helpers.

- Added vector stream codecs through `ToucanStreamCodecs`.

- Added deterministic, allocation-free unit-float and signed mutable-random helpers to `ToucanRandom`.

- Added double-precision smootherstep and clamping helpers to `ToucanEasing`.

- Added optional NeoForge shader registration.

- Added two-, three-, and four-component float uniform setters to `ToucanShaders`.

- Added simplified NeoForge config-screen factory helpers.

- Added supporting HUD, container-screen, model-part, and `GuiGraphics` mixins.

- Added tests covering the new interaction, tooltip, rendering, timing, random, caching, networking, state-cycle, skin-resolution, and crosshair-indicator APIs.

### Changed
