Description

We don't want layout shapes to be full traces but it would be pretty convenient to be able to add hoverlabels and text to them, for something like object-annotation or to label horizontal lines on plots.

Research direction

The issue does not identify any files, tests, or entry points. Start by locating the shape rendering and hover-label handling in the plotly.js codebase, then determine how layout shapes, annotations, and horizontal lines are represented. Done means shapes can display hover labels and text without becoming full traces, with coverage for the requested annotation use cases.
