docs: repository links now point to ragleap/ragleap-core (the repository moved from antonyrag/ragleap-core)
Remove hosted-only sections: RagLeap is open source only
docs: add Core Engine pages for AI Employees and n8n workflow automation Separate from the existing packages-scoped wiki content (ragleap-rag/ ragleap-graph) — these document core/ engine features that shipped in ragleap-core PRs #130/#133 (AI Employees) and #141 (n8n workflow automation). Each page has an explicit scope note distinguishing it from the surrounding packages wiki.
