Proposal: Add llms.txt / llms-full.txt for Echo v5 documentation

[iharshr]

Problem

AI coding assistants (like Cursor, Copilot, ChatGPT, and Claude) often struggle with Echo v5 because it introduces major breaking changes from v4 (such as echo.Context becoming a struct and the removal of the built-in logger). Without updated context, LLMs frequently hallucinate old v4 syntax.

Proposal

I propose adding an llms.txt and llms-full.txt file to the root of the repository (or the website documentation).

These files follow the emerging standard for serving high-density, markdown-formatted documentation specifically optimized for LLM consumption.

Benefits

• Better AI Code Generation: Developers using AI tools will get accurate Echo v5 code instantly.
• Fewer Repetitive Issues: Reduces GitHub issues caused by users pasting AI-generated v4 code into v5 projects.
• Lightweight: Easy to maintain alongside standard documentation updates.

Would the maintainers be open to a PR implementing this?
