feat(wear): add Compose wearable features

[Foxpace]

Adds the Wear OS domain and Compose presentation layers for recording, sensor display, menus, and phone launch.

What was added

• Wear measurement control, permission, sensor-query, observation, and sync use cases.
• Dashboard, menu, and phone-launch contracts, screens, and view models.
• Reducer and view-model unit tests with a coroutine dispatcher rule.

How it works

Wear screens follow the same intent-state-effect pattern as the phone application. View models invoke domain use cases to discover sensors, observe live values, control recording, transfer completed files, or request that the paired phone opens, then reduce results into immutable UI state.
