fix(useLocal): depuración de localStorage — groupOrder y categoryAssignments (#78)

[jansaldo]

El store de Zustand persistía en localStorage dos campos que acumulaban datos indefinidamente entre sesiones:

• groupOrder almacena el orden de drag-and-drop del label manager como Record<category, canonicalId[]>. Los canonicalId son UUIDs generados frescos cada vez que se procesan archivos, por lo que cualquier entrada de una sesión anterior es basura garantizada. Se excluye de la persistencia via partialize; sigue funcionando en RAM durante la sesión.
• categoryAssignments era dead code: setCategoryAssignments nunca fue invocado en ningún call site. Se elimina completamente del store y sus hooks.

Cambios:

• Se agrega partialize al config de persist para serializar solo serverHost, tutorialsSeen, excludedTags y excludedWords.
• Se elimina categoryAssignments / setCategoryAssignments del tipo, la implementación y los hooks exportados.

Cierra #78.

Summary by Sourcery

Restrict persisted Zustand local storage state to stable configuration fields and remove unused category assignment state from the local store and related hooks.

Bug Fixes:

• Stop persisting transient drag-and-drop group order data that becomes stale across sessions.

Enhancements:

• Add a persist configuration partializer so only relevant configuration fields are stored in localStorage.
• Remove dead categoryAssignments state and its setters from the local store and hooks.

Reviewer's Guide

Refactors the Zustand local storage store to stop persisting ephemeral drag-and-drop ordering data and to remove an unused category assignment field and its hooks, while explicitly whitelisting which fields are serialized to localStorage.

File-Level Changes

Change	Details	Files
Limit persisted Zustand state to non-ephemeral fields using partialize.	Add a partialize option to the persist middleware configuration for the local store Whitelist serverHost, tutorialsSeen, excludedTags, and excludedWords as the only fields serialized to localStorage Document via comments that groupOrder is excluded because it contains per-session UUIDs that become stale between sessions	src/renderer/src/store/useLocal.ts
Remove dead categoryAssignments state and its related API from the local store.	Remove categoryAssignments and setCategoryAssignments from the LocalStorageStore interface Delete the corresponding initial state and setter implementation from the Zustand store initializer Stop selecting categoryAssignments and setCategoryAssignments in useGroupOrder and useGroupOrderActions hooks	src/renderer/src/store/useLocal.ts

Hey - I've left some high level feedback:

• The partialize implementation is now the single source of truth for what gets persisted; consider using object destructuring (e.g., const { serverHost, tutorialsSeen, ... } = state) or a typed helper to reduce the risk of forgetting to include new fields when they should be persisted.

Pull request overview

This PR updates the renderer’s local Zustand store persistence to avoid accumulating stale session-specific data in localStorage, and removes unused state that had no call sites.

Changes:

• Add partialize to the persist config so only stable config fields are saved (serverHost, tutorialsSeen, excludedTags, excludedWords).
• Remove categoryAssignments and its setter from the store and exported hooks.
• Keep groupOrder in-memory only (no longer persisted) to prevent cross-session staleness.
