v0.5.1

Added

• Interactive HTML pages as task attachments. Ask an agent for an interactive explorer and it writes a self-contained HTML file under the task's attachments/, generated from the saved results and linked from ## Results. Each page leads with its main point and keeps exact values and method behind hover or toggles. The dashboard shows it inline in the task, one plot per embed sized to a phone screen, with an interactive figure in place of its PNG; only an explorer with linked views opens in the reading pane. Each runs in a sandboxed frame that follows the dashboard's theme, and the standalone export carries it. On request, an agent with an artifact-publishing tool publishes the same file. The showcase study gains an alpha explorer for its 25 portfolios; see communicate.
