CreateAvatarStructures performs scene/asset operations and changes the
wizard step mid-OnGUI, which resets IMGUI's layout cache and caused
"EndLayoutGroup: BeginLayoutGroup must be called first" errors as the
old step's layout groups were unwound.

Call GUIUtility.ExitGUI() right after CreateAvatarStructures to abort the
current GUI pass cleanly, matching the pattern already used by the entry
Remove button.

The wizard's FX Check step previously guarded only gesture-driven facial
expression transitions. Extend it to also detect and guard eye-blink
layers (EyeTrackingActive > 0.5), matching the standalone FX Gesture
Checker window.

- Surface detected blink layers with confidence badges, per-layer guard
  toggles, and detection reasons; auto-skip an entry only when it has
  neither gesture nor blink layers.
- Fold blink selection into the existing Apply Fixes flow so gesture and
  blink guards are applied to the same copied FX controller in one pass;
  status now reports transition, layer, and blink guard counts.
- Pre-expand gesture and blink layers after analysis so results are
  visible without a click.

Introduce FXGestureCheckerUI as the single home for FX result rendering
(gesture layers, transitions, blink section, confidence styles), which
the wizard step renders through.

Route the standalone FX Gesture Checker window's result rendering through
the shared FXGestureCheckerUI introduced for the wizard, removing its
duplicated layer/transition/blink drawing methods and FX GUIStyles. Pure
refactor: no behavior change.

New !Pawlygon/Tools/Patch Config Package Rules window for managing per-config
package requirements (configSpecificPackages) on PatcherHub FTPatchConfig
assets, edited entirely through SerializedObject so there is no compile-time
dependency on PatcherHub and Undo works for free.

- Auto-lists every FTPatchConfig in the project as a searchable, multi-select
  checklist (display name + rule count); selecting one exposes full
  add/edit/reorder/remove of its existing rules.
- Builds a rule from an installed-package picker that auto-fills package id,
  installed version, VCC URL, and pre-written missing/outdated messages
  (default severity Warning). Curated common avatar packages (Poiyomi,
  lilToon, Modular Avatar, GoGo Loco) sort to the top and carry their VCC
  install URLs; packages handled by the global PackageRules (VRChat SDK,
  VRCFury) show a "handled globally" note.
- Batch-applies a rule to all selected configs with a skip-duplicates guard.

Expose FTPatchConfigGenerator.GetFTPatchConfigType() so the window reuses the
existing PatcherHub type lookup.

Bump package to 1.5.0 and document the new features: the FX Check wizard
step, eye-blink detection in the FX Gesture Checker, and the Patch Config
Package Rules tool. Update the wizard workflow from five to six steps.
