Hold-label rendering depends on simulator flag and degrades silently

[malpern]

Tier: 3 (minor polish)

From the pre-release feature-gap audit.

Problem

Hold-action label rendering in the keyboard visualization and Context HUD is gated on FeatureFlags.simulatorAndVirtualKeysEnabled. If that flag is off, hold labels silently don't render even though the hold feature itself works. Relatedly, the contextHUDListEnabled experimental feature is default-OFF.

Evidence

• Sources/KeyPathAppKit/UI/KeyboardVisualization/KeyboardVisualizationViewModel+TCP.swift:355-356 — guard FeatureFlags.simulatorAndVirtualKeysEnabled else { skip hold label resolution }
• Sources/KeyPathAppKit/UI/ContextHUD/ContextHUDController+ShowForLayer.swift:115-117 — simulator-dependent fallback.

Action

Confirm the simulator flag stays ON for release (default), or decouple hold-label rendering from it.
