add curated llms.txt for agents

[thisisjofrank]

Replace auto-generated llms.txt with a hand-written curated index and add llms-full-guide.txt as an agent-oriented quick reference.

Both files are copied to the output directory at build time, with fallback to auto-generation for llms.txt. Updates middleware to serve the new file and fixes missing .gitignore entries.
