Release 0.1.3

• 0.1.3: the Datalayer Chat's agents read and edit the open Datalayer notebook or document (writes asked first, the file named), on the active tab or the one focused last (3382614)
• Datalayer Chat: the editor tools act on the open Datalayer notebook or document — the active tab, else the one of its kind focused last (the registry tracks focus and closing); the call is located first, its file named in the approval banner and the transcript's line, then run on that editor only, its tool-execution posted to that editor's webview panel, never the active one (d593cbb)
• docs: each of the editor tools' words is documented (TypeDoc's 0-warning check) (3be82d6)
• Datalayer Chat: the agents get the notebook and document tools Copilot has (082e29a)
• dev/docs: the Lexical comments plan and the username attempts log leave the extension's repository (2984f10)
