[Watch] 2 - Adapt gauges and navigation

[KacperKozak]

What to build

Adapt every existing Wear OS gauge and page-navigation behavior to the full usable rectangular Apple Watch display. Keep state and formatting equivalent while supporting both swipe navigation and side-knob navigation.

Source: docs/watchos.md and the approved watchOS parity plan. Execution: AFK, with integrated hardware validation in slice 8.

Likely files

• watch/wearos/src/main/java/app/vescape/wear/FrameGauges.kt — existing Wear OS behavior or wire-contract peer.
• watch/wearos/src/main/java/app/vescape/wear/MirrorScreen.kt — existing Wear OS behavior or wire-contract peer.
• watch/wearos/src/main/java/app/vescape/wear/MirrorState.kt — existing Wear OS behavior or wire-contract peer.
• watch/wearos/src/main/java/app/vescape/wear/TelemetryState.kt — existing Wear OS behavior or wire-contract peer.
• watch/wearos/src/main/java/app/vescape/wear/FrameReplay.kt — existing Wear OS behavior or wire-contract peer.

Implementation hints

Read current Android code, not historical alert-forwarding docs. Keep native phone truth and actions in vescape-core; do not make live wrist behavior depend on JS. Add bidirectional @parity links for equivalent contracts/logic and document verified platform differences in docs/watchos.md. New durable watch source belongs under watch/watchos/, not generated ios/. The local planning document will be included in the draft watchOS feature PR; this issue includes its relevant requirements independently.

Acceptance criteria

• All existing gauge metrics and units render without fitting the interface inside a circle; check 40mm and 44mm layouts.
• Crown moves vertical pages; swipes retain Android page structure and gestures, including gating interactions during page transitions.
• Fresh, stale, waiting and disconnected behavior follows the current Android reducer; ambient mode reduces refresh and marks stale values honestly.
• Use Android replay fixtures and contract tests to verify metric decoding, formatting, state transitions and ambient layout.

Implemented in 4016ddd on watchos.

Not verified: ambient rendering and the reduced ambient cadence — isLuminanceReduced cannot be forced on the simulator.
Not verified: crown rotation, swipe gestures and the transition gating — simctl drives neither the crown nor a paired-phone frame stream.
Pages for radar, weather, navigation, Move and Lights are placeholders; their content belongs to #487–#490.
