Add editable microphone automation rules and device type detection

[Wolbyworld]

Superseded by two separate proposals:

• Fix collapsed menu popover within available screen height #37 — popover viewport fix, with before/after screenshots and a native regression check.
• Add editable microphone rules and explained device type detection #38 — editable microphone rules and device detection, with GUI screenshots; draft pending hardware UAT.

The combined proposal below is retained for history.

---

Microphone selection currently follows one device order. This adds opt-in microphone rules so users can prefer device types and change those preferences when the laptop lid is open or closed.

• Open a persistent Microphone automation… window from the menu bar. Reorder types, choose Always / Lid open / Lid closed / Never, and restore default rules.
• Detect types from CoreAudio transport and input terminal metadata. Use limited, explained name hints for cameras and headsets; USB alone does not mean headset. Users can override each device or return it to Auto.
• Save rules and UID-based overrides. Respect Custom mode, Ignore, Never Use, and existing device priority for ties. Rules default to off; output selection keeps its current behavior.
• Give the device list a visible height on current macOS. This small prerequisite overlaps the layout fixes proposed in Fix menu popover collapsing on macOS 26 and sluggish drag-to-reorder #35 and Fix empty MenuBarExtra popover (device list was height 0) #33.

Validation:

• sh Tests/run.sh: 52 classification, selection, normalization, and persistence checks passed.
• ./build.sh: universal arm64/x86_64 Release build passed.
• Native preview UI: settings window, three connected input classifications, rule reordering, lid-condition edits, and override-to-Auto persistence checked.
• Independent code review of the fixed candidate found no blockers.

Physical microphone switching, lid transitions, reconnects, and audible input still need the hardware checks in Tests/UAT.md. Metadata does not establish a wireless dongle's physical headset link state. Name-based detection is a suggestion, and overrides can require reapplication if a driver changes the device UID.
