Renames the product across the codebase: Go module path, config/data paths, keychain service name, export file extension, build tooling, docs, and UI text. Sidebar brand mark now reads ">_ AlchementaryLink" with "Alchementary" in the connection-group gold accent colour, and the window title is "Alchementary Link".
