Stability and compatibility update focused on robust tooltip rebuilding.

Highlights

• Reworked tooltip ownership to a marker-based system (deterministic + idempotent).
• Removed fragile lore-position dependencies from previous behavior.
• Better compatibility with external /lore and enchant modifications.
• Preserves third-party/admin lore while rebuilding Descriptioner-managed lines.
• Stable enchant ordering for consistent visual output.
• Added background normalization command for bulk cleanup.

Admin Command

/descriptioner normalize [batchSize]

• Runs in background batches.
• Useful to normalize existing items after updates.

Compatibility

• Works with 1.21.x (verified on 1.21.11 & 1.21.4)
