ragleap-tools v0.1.0

Initial release: 12 stateless tools (calculator, datetime, unit conversion, JSON/CSV parsing, text utilities), sandboxed file ops with symlink-escape protection, and optional ragleap-rag-backed document ingestion. 51 tests including real security verification (AST-whitelist calculator, path-traversal/symlink-escape rejection). Deliberately excludes code execution, web search, HTTP fetch, and business-system connectors — each needs its own security-focused design pass.
