PR Checklist

• Have you checked if it works normally in all models? Ignore this if it doesn't use models.
• Have you checked if it works normally in all web, local, and node hosted versions? If it doesn't, have you blocked it in those versions?
• Have you added type definitions?

Description

Add features

• Add 'insert' operation to lorebook inject types in lorebook.svelte.ts
• Implement loreinjectParser using inject-based approach in index.svelte.ts
• Support both {{loreinject::name}} and {{lore_inject::name}} syntax
• Update CBS documentation for loreinject function

Instructions

How to use the new loreinject functionality:

1. Create a lorebook entry with @@inject_at decorator:
   @@inject_at myTarget This content will be injected when {{loreinject::myTarget}} is used. You can include multiple lines and complex content here.

2. Use loreinject in your prompts:
   {{loreinject::myTarget}} or {{lore_inject::myTarget}}

3. How it works:

• It works almost same as {{position}}
• The lorebook entry must start with @@inject_at <targetName>
• The lorebook must be active (keywords matched) to be available for injection
• Multiple lorebooks with the same target name will be combined

Example use case:

• Create dynamic character descriptions that can be injected contextually
• Build modular world-building content that can be referenced anywhere
• Implement conditional lore injection based on active lorebooks

I can't find what 'depthPrompt' work. AI said it is character's system prompt and need to use 'loreinjectParser', but well.. I'm not sure.

Whatever depthPrompt is, there will be no errors in depthPrompt caused by 'loreinjectParser'.
