Preserve custom books when using /book commands

[XxFran10xX]

Essentials /book rebuilds signed and writable books from content-only metadata, stripping ArmourShop covers and item identity. Delegate custom-book commands to Essentials so its ownership and permission checks remain in place, then synchronously restore the original item data, pages, and matching signed/unsigned ItemsAdder cover.

Vanilla books and other plugins' book commands continue through their normal handlers. Title and author edits remain with Essentials. Synchronous restoration avoids deferred inventory-slot overwrites. Command failures are logged and reported to the player, and issued-command logging is retained.

Validation:

• Maven verify: all 30 tests pass; GitHub build is green.
• TFMCDev01 (Paper 1.21.10, Essentials 2.22.0-dev+60, ItemsAdder 4.0.18): eight integration checks pass using a connected test player.
• Hazel's Notebook: sign, /book unsign, edit both pages, /essentials:book sign, and change title; page text and the correct cover/model survive.
• Other-author conversion is denied without essentials.book.others and succeeds with it.
• Local model book keeps custom name, lore, arbitrary custom data, MMO item identity, and pages.
• Vanilla /book conversion still works. Temporary test items and permission overrides were removed.

📝 Summary

Summary by CodeRabbit

• New Features
  • Custom book skins are preserved when using Essentials’ /book command to convert custom writable books into written books, or written books into writable books. Original pages and appearance remain intact, while the converted book retains its amount and, for written books, its title, author and generation details. Errors during command execution are reported to the player.

Walkthrough

The plugin registers a listener for Essentials book commands. The listener delegates eligible commands and restores custom-book data when Essentials converts the held book to the other book type.

Merge Risk: 🔵 Low · up to e306a

The synchronous restoration appears consistent with the intended behavior. Merge risk is bounded, but a focused preservation test would protect the core feature from regressions.

39-51: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Exercise the production restoration helper.

All BookCommandSkinListenerTest cases inject a replacement restoration function. No test source references restoreConversion or the default listener constructor. Therefore, the tests do not detect regressions that drop original pages or custom metadata, or that fail to retain Essentials' resulting title and author.

Add one focused test with a real BookCommandSkinListener.restoreConversion call and assertions for those fields.
