gramps 87509bcf99 docs: restructure TASKS.md into a catalog — one file per task in TASKS/

TASKS.md is now the index (status table, open items, research pointer).
33 files: 32 task files + 1 research facts file. The full take-saga
narrative and all design decisions are preserved verbatim; the catalog
makes the queue readable without opening every task body. Schema and
AGENTS.md updated to reflect the new layout.

TASK 16 — Kill infinity display (no-game backdrop fallback)

Catalog: TASKS.md — status and requirements live here.

Goal: when no full-screen game is detected, show a static branded placeholder instead of capturing the primary display (which causes the infinity mirror effect).

Status: ✅ Shipped

Changes:

ResolveAutoCaptureKey() returns null when no full-screen game is detected (was: primary monitor)
ReacquireScreenCaptures() — clears stale CaptureKey when auto == null (handles DB upgrades); skips AcquireAsync when no keys are set
SeedLiveBackdropAsset() — sets AssetId on the backdrop element itself (NOT a Background source); called from ReacquireScreenCaptures() after EnsureBackdrop() guarantees the element exists
Source.DisplaySource falls back to _imageSource when VideoImageSource is null for live captures
Assets/live-backdrop.jpg — user-provided image, added as <Resource> in csproj
ResolveOutputFrame() in compositor — Source { IsLiveCapture: true, CaptureKey: not null } already skips null keys; fallback pattern Source { AssetId: not null } picks up the static image

Rendering flow:

Scenario	Preview	Compositor
Game detected	Live capture (opaque, covers static asset on backdrop)	`ScreenCaptureManager.GetLatestFrame`
No game	Static image via `DisplaySource` → `_imageSource` on backdrop	`StaticPixelCache.Get(assetId)`
Manual capture pick	Live capture	Live frame
