What do the four icons on a robot in the board menu do?

How to get there:

1. Open the board menu.
2. Tap the robot you want to act on: you get its name, its status and four actions. What each icon does:

• 💡 Light bulb: makes that robot blink blue. Purely for identification: "which of these four is the one at 12%?" Useful before lifting the board.
• ⚡ Lightning bolt: send this robot to the charging dock now.
• ⟳ Square / arrows: disconnect and automatically reconnect the Bluetooth link. See the known-bug note below.
• 🗑 Trash: unpair / remove the robot. There is also a + button to search for and add a robot. After adding, the app checks whether it is ready; if it needs calibration you will be told to lift the board and place it on a corner.

Known bug: reconnect currently behaves like unpair. A regression (it worked in earlier versions, and appears to have broken when the bolt icon was added). Caught on the deep-dive call and reported. Workaround: re-add the robot with +, or use "Relaunch robot onboarding".

Note that these icons have no tooltips or labels in the app today, so customers ask what they do. Expect it. App screenshot of the board menu with a robot expanded. The four icons (bulb, bolt, reconnect, trash) and the + button annotated with callout labels.
