Add Tray Privacy Indicator Anchor v1.0

[sb4ssman]

Adds Tray Privacy Indicator Anchor (v1.0): reserves stable tray space for the Windows 11 privacy indicators. Location, microphone, camera, and Copilot placeholders stay visible — dim when idle, bright when in use — so tray sections stop shifting when Windows briefly pops its native indicators in and out (a constant nuisance when Widgets/Web Experience Pack polls location).

Highlights:

• Persistent placeholder icons with four visual states per icon: idle, active, disabled/unavailable, and active-while-blocked (a muted or shuttered device still demands attention when Windows reports attempted use).
• Evidence-specific tooltips instead of a generic "disabled" label: privacy-settings denial, system/admin denial, policy, location service off, endpoint mute (laptop Fn-key), device problems, and Windows 11 CameraOcclusionInfo hardware shutter/kill-switch reports on supported camera drivers. Each icon click opens the Windows Settings page matching the reported reason.
• Event-driven state: registry (ConsentStore/policy/AppModel), device-access, device-topology, audio-endpoint, and camera-occlusion notifications — no polling sweep. Copilot process activity is checked once per minute; a five-minute reconciliation repairs missed notifications.
• Smart grid layouts sized from the live taskbar height (single row on standard taskbars, compact grids on double-height), plus fixed row/column modes, fill order, and short row/column placement and alignment.
• Tray placement before icons / before network-volume-battery / before or after clock / after Show Desktop via a leased, marker-tracked tray column, plus two experimental Start-adjacent positions.
• Independent idle/active/disabled/glow/slash colors, and steady, breathing, or radiating active glow drawn inside the reserved slot (never changes taskbar width).

Screenshots (also embedded in the mod readme):

Tested live on Windows 11 (primary taskbar): native indicator suppression with mirrored state, in-use highlighting from real streaming, hardware camera shutter detection and release/reacquire on settings changes, evidence tooltips and reason-aware settings click-through, smart grid on single- and double-height taskbars, settings reload, Explorer restart, and full system restart.
