add: tool to remove an index documentation

add: able to index a llms-full.txt url directly too, everything tested

add: it all seems to work!

tested, not sure but indexing a llms-full like txt might also be working already thrgough the supabase example

add: good version txt index parsing

add: seems to work: llms.txt + scraping working, next step is indexing a llms-full.txt

add: might be broken, switched to playwright scraping => more robust + more parallel

feat: index documentations that don't provide the llms.txt

add: images

add: update README

add: MCP with documentation indexing and retrieval
