v2.13.0 — DAT SDK 0.9.0: newer glasses supported

Meta DAT SDK 0.5.0 → 0.9.0 (issue #55)

Newer glasses (Ray-Ban Meta Gen 2 "Blayzer Optics", Meta Glasses, Oakley Meta) were invisible to OpenVision — the pinned SDK predated the hardware. This release migrates to SDK 0.9.0, field-verified on Ray-Ban Meta Gen 1/2 (Wayfarer) and Blayzer Gen 2.

What changed

• SDK 0.9.0 + new camera lifecycle: DeviceSession → addCamera → camera.stream (session must reach .started before the camera attaches).
• New: "Install/Update Glasses App" button (glasses settings) — stages the on-glasses developer component (DWA) via Meta AI. Without it, sessions die with "Device unavailable" / "Session ended by device".
• Session error-stream + device compatibility diagnostics; SDK log guidance in the issue.
• Stream errors no longer pop a modal when the app is backgrounded (the raw codec pauses by design on screen lock).

⚠️ Required one-time setup for source builders

SDK 0.9.0's App Model needs a complete trust chain — app-side code alone is not enough:

1. Wearables Developer Center → your project → Configuration: fill your Apple Team ID and toggle Camera access ON (with rationale). Old projects created in the 0.5.0 era lack both.
2. In the app: Unregister → Register (re-issues the grant).
3. Tap Install/Update Glasses App and complete the Meta AI hand-off.

Requirements: glasses firmware V126+, Meta AI app V282+, iOS 17.2+.

Thanks to @BarryLaminack for meticulous field testing on Blayzer Gen 2.
