…tion, simplify track auto-creation Issues addressed from architecture review (#1.1, #1.2, #1.3): **1.2 — Tracker encapsulation (SimModel)** - Make `tracker` private; no view can access OpenCVTracker directly - Add facade methods: `isTrackerReady`, `resetTracker()`, `resizeTracker()`, `initTracker()`, `trackFrame()` — the full tracker API now lives behind the model boundary **1.1 — Atomic video source activation (SimModel + VideoSourceControlNode)** - Add `activateRecording()`, `activateUpload()`, `activateBundledVideo()` that set all related properties (isWebcamVideo, frameRate, totalFrameCount, currentWebcamBlob) in a single call, eliminating visible intermediate states - Consolidate all activation logic into the `selectedVideoProperty.lazyLink` handler — the single canonical dispatch point - Remove scattered direct property writes from the webp upload handler, `storeAndLoad`, and the webcam panel `onVideoReady` callback - Fix pre-existing bug: `onWebcamReady` was being called twice in the webcam recording and file upload flows (once from the lazyLink, once directly) - `VideoSelectedCallback` type simplified to `(url: string) => void` since fps is now owned by `activateBundledVideo` **1.3 — Track auto-creation (SimModel + AutoTrackerNode)** - Add `addTrackAndActivate()` to SimModel; replaces the 8-line view-side block that read `tracksProperty.value` directly after `addTrack()` to find and activate the newest track https://claude.ai/code/session_01LAwGKZUVqF9MNrUgaFtFyS
