fastfind v0.3.0

MCP server for grounded agent file discovery. Two tools: search (files/folders by name, type, size, date) and grep (index-scoped parallel content search). NTFS MFT indexing kept resident in RAM. Assets: fastfind.exe (standalone binary + MCP server, run fastfind install --apply) and fastfind.mcpb (double-click to install into Claude Desktop).
