Three small changes to PDChat's voice controls, delivered together because they share one surface (Magic Suite MS-28499, MS-28498 and MS-28518).

What changes

• The voice picker shows what the microphone is doing (MS-28499). It used to mark its choice with each option's selected attribute. Once the user has picked an option, the browser stops moving the selection when that attribute changes, so after Mic off the ear button resumed listening while the picker still read "Mic off". The select's value is now set from the voice state: Mic off while the microphone is off, otherwise the running mode.
• A Mic off badge on the voice button (MS-28498). While the microphone is off, the button keeps its mode icon (HAL eye, microphone or ear) and carries a small badge, styled like the existing paused badge. The icon is the new PDChatIcons.MicOff, fas fa-microphone-slash by default. Set it to an empty string and no badge is shown.
• An optional shortcut that cycles the modes (MS-28518). New VoiceModeShortcutKey parameter, a KeyboardEvent.code such as "KeyM", null by default, so existing hosts get no new keyboard behaviour. With it set, Alt and that key, while focus is in the chat, cycles Mic off, HAL, Dictate and the wake phrase mode (when offered). Ctrl with Alt (AltGr) is ignored, read aloud is untouched, nothing happens while the chat is minimised, and the picker's tooltip names the shortcut. The demo sets KeyM.

The PDChat documentation page covers the new parameter, the badge and the shortcut.

No change to the toolbar's width: the badge sits inside the existing button, and in a corner-docked chat the picker is already reduced to its arrow.

Tests

• PanoramicData.Blazor.Test/Components/PDChatTests.VoicePickerAndShortcut.cs: 26 component tests. All 284 PDChat tests pass.
• tests/pdchat-voice-controls.spec.ts: 3 Playwright tests. They cover the picker after Mic off and the ear button, and after a reload. They cover Alt+M inside the chat and in a text box outside it. They also check the badge appears only while the mic is off. All pass in Edge.
• Red-checked by breaking the change 13 ways, one at a time; every break failed at least one test. Restoring the original per-option selected markup fails the first Playwright test at the exact step (expected Hal, received MicOff).

Magic Suite will set VoiceModeShortcutKey="KeyM" on its PDChat when it takes this release on 4.8.
