Add llms-full.txt comprehensive API reference

[fantaJinMode]

Description

Adds llms-full.txt, a 2,100-line LLM-optimized full reference document for @linkforty/core. It covers every API endpoint, TypeScript type, configuration option, database schema, and integration pattern in a single, structured file designed for use with AI coding assistants.

Benefits

• Enables AI tools to generate accurate, type-safe integration code without hallucinating API shapes
• Single file covers the full surface area — no need to browse source or scattered docs
• Complements the existing llms.txt (concise) / llms-full.txt (complete) convention
