feat: add AI agent instruction files to templates

[ozsay]

Description

This PR adds AI agent instruction files (AGENTS.md and CLAUDE.md) to both the backend-and-client and backend-only project templates. These files instruct AI agents to prioritize skills-based reasoning from the skills folder over general pre-training knowledge when working with Base44 tasks, ensuring more consistent and framework-specific behavior.

These files will be included in new projects created with base44 create, providing AI agents with context-specific guidance when working within Base44 projects. The files use standard conventions (AGENTS.md for general AI agents, CLAUDE.md specifically for Claude) to ensure broad compatibility with different AI coding assistants.
