[DOCS] llmx-ctx*.txt

[mecampbellsoup]

Issue Type

• Existing documentation (e.g. typos, errors, outdated information)
• Suggest new documentation that is currently missing

Current Behavior or Documentation Gaps
The README only mentions the existence of llms-ctx.txt, but NOT llms-ctx-full.txt.

If we use the full version, should we expect better results from Cursor chat/dialogues?

I would like it if the README discussed the tradeoffs of using the "full" data file, e.g. better data for the bot so better dialogues, but more tokens hence more cost.

Also, what is the purpose of llms.txt? It doesn't seem to be documented.
